Okay, I've found a "bug" - not too sure who's side it's on. It's a little weird, but all chaos breaks loose when I hit it: Step 1. Run Windows XP in Parallels Step 2. Establish Remote Desktop session from OS X to a Microsoft system Step 3. Copy (as in cut-n-paste) something to the clipboard in the remote Microsoft system Step 4. Paste into a local application on OS X Immediately Parallels locks up, remote desktop freezes, and the local app in OS X freezes. This may sound like a totally bogus thing, but I'm always doing these tasks in remote desktop - any workarounds?
