My primary reason for using Parallels is to run Outlook. The one annoying thing is that the Outlook notification window for email does not go to the highest z-order for display on the Mac, it only goes the highest in the VM. It would be great if you could somehow have the Outlook notifications create Growl notifications for OS X. Just a thought.
Going to bump this. It is VERY annoying that Outlooks new email notification does not come to the top of all windows, Mac ones included.
