Hi
It works, it maintained the resolution in more than one open window.



Very good
Thank you.

@basso: When you share the same Server with multiple clients they all show the the same desktop.
VNC clones a desktop, it isn't like an RDP Server where all sessions have there own desktop.


In this case, Viewer Listening is used.
The sessions are called by UltraVNC SC (Single Click).

The VNC Window display windows do not maintain the correct resolution size when more than one is opened simultaneously by more than one connection, always changing to the current connection.
This is an old problem that persists.

If "Even" is checked, the resolution remains the same, and the size ...

When attempting to transfer a file while it is open, the program freezes and closes if the "forced stop" button is clicked.

The file size becomes very large; there may be an error in calculating the size with the file open.

You posted the wrong download URLs.

Following the right ones:

- https://uvnc.eu/download/1800/UltraVNC_ ... _Setup.exe
- zip-file is missing

FileTransfer works fine
Congratulations
Thanks

There was no point in changing the port. I changed from 5900 to 2000 or 59000, the same happens. I changed the public IP and the problem also continued.
