There was a particular issue with RD Tabs that was causing some confusion for Vista users. It's purely cosmetic, so feel free to skip this update, if you so desire.

- One of the resource watchdogs that RD Tabs spawns was causing confusion for Vista users. This is because in XP, this thread is "hidden" and not visible by normal means. In Vista, however, it pops right up in your Task Manager task list with its bold scary title, "Error: Low on Desktop Heap." The thing is, this watchdog has a scary title, but it's only of concern if you actually run low on Desktop Heap. But when you see it in the task manager, even if it's not active, it looks as if you ARE low on desktop heap, even when you are not. So I renamed the title of the watchdog thread to "RD Tabs Resource Monitor" so it's less confusing. It will now only say "error" if there is an actual error to be concerned about. Sorry about the confusion!
