Re: UltraVNC 1.6.1.0 - Feedbacks

Someone insisted on changing the default location to %appdata%
1) vncviewer.exe folder is used
2) When this folder is not writable, %appdata% is used
3) when this folder has no write access %TEMP% is used

Verified the src CSIDL_COMMON_APPDATA %programdata% isn't used

8 colors

If you set 8 colors and save and connect to a server.
close viewer
open viewer and select same host
Are the 8 colors set or is the value lost ?

Thanks

Re: Problem with the remote PC's primary display when the remote PC and the local PC each have two monitors.

Can you also provide the UltraVNC Viewer display settings?
There are a lot of options.

What do you want 2x 2K displayed on 2x HD resized or with scrollbars?
Are you using the DDEngine, should be indicated by the Viewer?

Thanks

Re: UltraVNC 1.6.1.0 - Feedbacks

@wojtek: "AutoAcceptIncoming = 1" is still the correct parameter, just tested.
This can be set via Viewer -> Options -> Security

Server need to be SC or a full server started with -sc_prompt and the viewer need to have "AutoAcceptIncoming = 1" set to show this box
