I've been using PD5 for a while, and thought I would try out PD6 to see if it offered anything worth upgrading for. Right away, I notice that some of the keyboard shortcuts that were working correctly in a Win7 guest under PD5 are now broken in PD6. For example, pressing Ctrl+F4 is a common Windows shortcut to closing the active document/tab, and that worked correctly under PD5. Now though, pressing the same keyboard shortcut transfers control to Mac OS X. I have to uncheck "Enable Mac OS X System Shortcuts" from the Parallels preferences dialog before this starts working again. Ctrl+F2 similarly transfers control back to Mac OS, but Ctrl+ any of the other function keys is sent to the Windows guest. Any way to fix this?
