I solved this by executing this in the terminal:
defaults write com.parallels.Parallels Parallels.MainApp.SSManagerXPos 0;defaults write com.parallels.Parallels Parallels.MainApp.SSManagerYPos 22
I can only select it when it appears on all windows using a hot corner but reverts off the screen after it is selected. There is no "Window >> Zoom" in the file menu.
I am running Parallels 3.0 and I try to open the "Virtual Machine Snapshots" dialog, it opens off the screen. I don't see it minimized or on the screen but when I click my hot corner for "All Windows" I am able to select it. How do I get it on the screen (note: I am only using one monitor)...
