It's a minor thing, but it would surely be only a minor thing to fix, so here's my wish: I use Paralles in full screen running most of the time on my MBP 17". In the office, I have an external monitor with 1600x1200, at home and on the road I use the builtin 1680x1024. When I put the machine to sleep on either screen, and wake it up with the other screen, Parallels does not recognize the screen size change, so I have to select "OS Window" and then again "Full Screen" manually to have the full screen size adjusted. As said, it's a minor, almost cosmetic thing, but as Parallels tracks the VM screen size changes in all other cases perfectly (OS window size change, transition from and to full screen), I guess it's only a matter of adding a screen size check trigger when the machine wakes from sleep - so I hope this will be done in a future update
