The failure has been in one of two ways. One way is when the File Transfer window just closes. The VNCViewer window will not respond in any way. Most of the time I can't get it to minimize or close. If it minimized, it immediately reports "VNCViewer is not responding". I usually get this message ...

Had a look at v1.2.1.5 and I still can reproduce viewer crashes - or now more often: viewer hangs (app hangs and does not repsond anymore). It looks like the viewer doesn't eat the cpu anymore (25-50% cpu usage on disconnect) but now there's something else strange going on... Rudi did you change ...

hmm, let me ask one more question. Is it a server or a viewer side improvement? From what I've understood it is a server side improvement. Just to be sure...
As I understand there were 2 issues resolved.

1) client-side/server-side - packet processing limitation was restricting how much data could ...

This problem was resolved in test build 1.2.1.6 available here:
http://forum.ultravnc.info/viewtopic.ph ... 13#p102032

**Server was indeed using the menu to send packages.
As test, changed the method, FT is faster but screen updates are to slow to be useful during transfer.
The transfer is direct without the menu, this should overcome the service issue's where the menu and winvnc run in seperate sessions.

I ...

This are 2 different things, but as file transfer is client/server also related.
I understand the fix you put in the client to increase the amount of KB processed while adhering to 1000 packets/second limitation is a separate issue.

It seems even with that change Prisma/OP is still seeing stalled ...

But on connections having hangs the new viewer shows no difference.
Tested with connection speed of viewer cable 150mbit down/10mbit up and server side adsl 50mbit down/10mbit up.
Transfer mostly hangs. This results in an average speed of 350 kb/s which is far away from physical possibility. http ...

This has been bothering me for a while but I never had the time to isolate the problem.

Client: WinXP, Win10 - UltraVNC 1.2.1.2 100Mbps LAN
Server: WinXP - UltraVNC 1.2.1.2 GigaBit LAN

When I run UltraVNC server as a service, file transfers are extremely slow and choppy (transfer some, then stuck ...

Give it a try and see if it resolves your problem.

You need to differentate between install when running as service
and as application.

Running as service the silent is needed, else it ask to kill the service.
In 1.0.91 Running as application there was an error, that the dsm was buzy ( this doesn't exist in 1.0.92)

To fix stuff i need to ...

mouse:
The auto mouse has an impact.
Viewer send mouse position.
If mouse is moved manual on server site, server send mouse mpoition to viewer.
I guess that auto mouse moves by server are not detected -> it fall back to the origal viewer position -> jump effect.
So I turned off auto mouse to ...

You need to select to install Server Slilent... not full.
[v] Start service
Thanks, that would get rid of the prompts, but the (now not reproducable) problem I was seeing is the install time prompt to remove server was hidden and obviously the progress bar stopped waiting for user input ...

Does anyone know why the cursor is a bit jumpy when Track cursor locally is enabled.

What I'm seeing doesn't seem to be related to queued mouse movements as it will often happen when the mouse pointer is just sitting there. It seems to happen more when I hover over (mouse over) objects.

The ...

I have been using "Auto Select" best connection options and track mouse locally for a long time and could reproduce the crash at will for the longest time, but with the build above, none of my machines can reproduce the bug anymore (and I had a few that were real stalwarts)

1Gbps, 100Mbps, single ...

Is it during login or later on? Are server and client same version? etc.

I could try to reproduce also if there are more details.

I just did another remote install and this time the prompt asking to remove the service comes up in the foreground. I don't know why it didn't the first 2 installs.

Yes, confirmed fix in these beta builds:

I can confirm this release fixed
vncviewer.exe crashes on first few connects, then it works

The upgraded viewer works with 1.0.9.1 and 1.0.9.2 servers without crashing ...

Thanks, totally missed it first time around.

-update installer start server after installation (option)

How do I enable this option?

I tried the update installer and the 1.0.9.2 release fixed the previous overwrite error with securevncplugin.dsm

However after the update installer closes a server running as an application (vs service) it ...

Minor UI bug.

For the 1.0.9.1 client, the IP address area in the upper right of the window (under the title bar, to the left of the upload/download graphical bars) seems to be off by one pixel in its placement. It appears to be 1 pixel to high. If you look at the very thin darker edge line right ...

Sorry for wrong terminology (close/kill vs crash)

Will test/confirm 1.0.9.2 updater when it becomes available.

Thanks.

In case it helps, I duplicated the problem and recorded more info:

After going through the update prompts, the install starts extracting files. Then it starts installing files. Once it reaches securevncplugin.dsm, winvnc.exe crashes and puts up the "winvnc.exe has encountered a problem and needs to ...

Is the "update" (as opposed to "full") version supposed to allow you to upgrade a VNC server running as an app, or only as a service?

I have a couple of machines being updated remotely over a VNC connection. The ones with the vnc server running as a service updated properly using the "update ...

RC23 is actually 1.0.9.0 RC2.3 which led to 1.0.9.1

There might be some ctl-alt-del stuff for win7 still evolving on the RC2.3 thread.

It happens often when auto-mode is selected because that is what I have set as the default.

When I change the connection settings to something other than auto, it either never happens or doesn't happen often (I can't be sure it never happens, but I don't remember it happening)

Also when the ...

Is this crash something that could be (or you planned to) address in this release?

vncviewer.exe crashes on first few connects, then it works
[topic=17917][/topic]

I saw this first in 1.0.8.2. I have now updated both client and server to 1.0.9.1 and the problem still occurs.

Basically upon first ...

Tried with server running mirror driver and crash doesn't happen (in the viewer), but as usual with a race condition, the change might have nothing to do with the actual cause, just might be changing the timing of events to avoid the issue.
