I often have both a VNC client window and several X windows open (via Xming) at the same time on my Windows XP desktop. When this happens, the X windows, especially emacs and firefox, often lock up or behave erratically. I am pretty sure I have narrowed this down to contention over the clipboard. I wasn't really able to find any options controlling this behavior in either Xming or VNC. Is there a solution to this problem? Right now, I have to close VNC when I am actively using emacs...

Restarting the clipboard might help, not sure if this'll work on XP, on Windows 7: taskkill /IM rdpclip.exe /F start /MIN rdpclip.exe This has some more information here.
