Another interesting annoy bug that I noticed in Parallels. This is not one time, it happens every time. When I have the Windows Vista running in Parallels and if I keep it idle for few hours then you can’t do anything with that OS when running under Parallels. The OS will be grayed out, and will not respond to any keystrokes or mouse events. It happens either in full-screen, windows or coherence mode.
The only option left is to quit the Parallels and restart the OS back. They should let user know that the OS is in sleep mode; and should allow to start the OS directly, by identifying the underlying OS state.
Actually it is not a bug. Vista goes to sleep in 1 hour by default. Parallels mapping its sleep state to virtual machine pause. To wake up Vista from sleep you should click on menu Actions->Continue or click on Start button on toolbar.
As a workaround you can disable Vista sleep options in Vista control panel.
Thanks Andrew…I figured this out…I noticed in my case that the start and continue options are grayed out allowing me nothing other than closing and restarting. May be I should retest this on my another Macbook pro.
