I've just setup remote access to a Windows XP box using RealVNC. When the user runs an app, they expierence issues with "screen painting" – the screen doesn't paint well, except for a radius around the mouse cursor.
The app is displaying a calendar. I am not sure what it is written in (think it is a .NET app)
Have no problems getting/staying connected. Initially it seemed to be working fine. I have looked through all of the settings as far as compression and speed.
I can replicate the issue from more than 1 location. The hosting Internet connection is DSL.

In my opinion RDP works better than VNC. However if you must use VNC, and there are plenty of situations where RDP doesn't work, then I've had much better luck with TightVNC and using the Mirage Mirror Driver.
