I use Parallels primarily for running programs that won't run in Mac OSX, namely VMWare Remote Consoles, things that require IE6, etc. I recently upgraded to version 5 of Desktop and now, the Control+Alt combo on the VMWare remote consoles doesn't actually release the console - it still says "Press Ctrl+Alt to Release" and I can't do any actions on the other Windows. Is there a keybinding somewhere I can't see that is preventing this from working? It worked in version 4.
Ctrl+Alt key combination is used by Parallels. You can change it in the Parallels Desktop preferences.
