I've been using Remote Desktop to connect from a Windows Vista machine to a Windows XP machine. Everything used to work fine, but a few weeks ago I found that I could not drag things with my mouse. I can click on things just fine, but I cannot move or resize windows or select text with the mouse. I did some experimenting, and it seems that the remote machine behaves as though it gets a mouse up event shortly after it gets the mouse down event, even though I am still holding the button down. On both machines, things work fine outside of Remote Desktop.
I did reinstall the OS and software on my Windows Vista machine a couple of months ago, and that might have been about the same time that this problem appeared. I don't frequently use Remote Desktop, so I can't be sure.
Does anyone have any suggestions?
