I installed the Parallels-Desktop-1862-Mac.dmg beta tonight, and ran into a serious problem that will most certainly prevent me from using it! I run parallels on a Mac mini & LCD display that sits next to my cinema display hooked up to my G5 tower. I use Synergy (http://synergy2.sourceforge.net/) to share my mouse and keyboard between the two machines. When I move my cursor off the cinema display (G5) screen, it shows up on the Parallels (Mac mini) screen. When my cursor is on the Mac mini in Parallels, anything I type on the keyboard goes straight into the Parallels guest operating system (Windows XP or Linux). So, for instance, to log into Windows XP, I place my cursor on the Mac mini and type Control-Command-Del. This has been working flawlessly for ages- until... Tonight, after installing the Parallels-Desktop-1862-Mac.dmg beta, Parallels completely ignores Control-Command-Del! At first I figured it must be something else causing this. I did the following things to try to figure out what was wrong: Checked my Synergy server/client configurations Opened System Preferences > Keyboard & Mouse > Keyboard Shortcuts and clicked Reset to Defaults to make sure I hadn't accidentally overridden the key combination Verified that Parallels Preferences wasn't using that key combination for something else Rebooted my router, just in case the router was somehow causing stuff to be dropped or malformed on transfer over the network Checked to see if these keys work in other Mac OS X applications outside of Parallels on the Mac mini - they do work in other applications So the problem is only within Parallels, and nowhere else. Then I uninstalled the beta, and reinstalled the previous version (1848), and like magic, the keys were again accepted in Parallels! My unfortunate conclusion: Something must have changed in this beta that causes some keys not to be accepted from Synergy! Sadly, I will not be able to update Parallels Desktop until this is fixed! Any suggestions??
