I just installed UltraVNC 1.4.3.6. on multiple PC's
Now I can't copy the clipboard from or to any of them.
They are all running Windows 10.
I had an earlier version of UltraVNC on all of them and the clipboard worked fine.
I do have Clipboard, Enable Automatic Synchronization checked on all of them.
After more 2 000 000 (two million) views on forum for 1.5.0.x development versions... and 1.6.1.0, 1.6.3.0-dev versions
A new stable version, UltraVNC 1.6.4.0 and UltraVNC SC 1.6.4.0 have been released: https://forum.uvnc.com/viewtopic.php?t=38095

I can't copy with the clipboard
Re: I can't copy with the clipboard
Does anyone know why "Automatic Synchronization" for the clipboard isn't working in ver. 1.4.3.6?
Re: I can't copy with the clipboard
Do you have the file transfer window open (or minimized)? In this case the clipboard transfer will not work. This had never worked (for me). I tried it with this version of uvnc and after closing the transfer window the synchronization worked again.
Re: I can't copy with the clipboard
I don't have the file transfer window open.
I can transfer automatically from the host to the client.
It won't transfer from the client to the host unless I select the UVNC icon in the top left, Clipboard, Request all formats now.
Thank you,

Re: I can't copy with the clipboard
And what format are you trying to transfer? Just text, html or rtf. Or images?docfxit wrote: 2024-10-03 04:27 I can transfer automatically from the host to the client.

(for images you need to "request all formats now") looking at those options.)
Re: I can't copy with the clipboard
I would like to copy mostly text. But it could be anything.
Re: I can't copy with the clipboard
I'm currently working with ver. 1.8.2.4.
Has there been any progress in automatically copying from the client to the host? The copying from the host to the client has always automatically put the clipboard from the host as soon as it gets changed over to the client in Windows 10.
We have had a number of versions since this original post. I'm wondering if there has been any progress in making this happen.
Another question is if it can't happen automatically, is there a key sequence on the client that would transfer the clipboard to the host. Maybe someone knows of a program that will transfer the clipboard.
Thanks,
Docfxit
