I usually use Coherence, but I have an issue with one program I use that does not redraw correctly in this mode, so I switched to fullscreen, which I haven't used in a while. I have one external display I use along with my MBPs built-in screen and have no issue with it with Coherence. When I went to fullscreen, I had very strange behavior that looked like constant flipping back and forth between Mac OS Spaces. The external display remained black. When I looked at the Windows 7 Display settings, it indicated I had 4 external displays, all matching the resolution of my MBP display! So something is very fishy. I tried reinstalling Parallels Tools to no avail. Any idea what's going on here and how to fix it? I have Full Screen set to use all displays.
