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.
