The window resize button on my VirtualPC is dimmed and when I do rezise to\nfull screen, it resizes only partially. I've never had trouble with this\nbefore. I've always been able to maximize fully and resize to a smaller\nwindow. Now I get scroll bars when I do that. I've uninstalled and\nreinstalled Virtual Manchine Additions. Any ideas what is causing this and\nhow to fix it?
