I have a repeatable issue with Vista x64 - when trying to remote control a machine using Terminal Services (RDP), instead of connecting it pops up a "blank" instance of MSTSC.EXE and doesn't do anything, until it times out.

I found a workaround, though - if I go to C:\Users\[username]\AppData\Local\Temp and double-click on the RDP connection file before the timeout, I get a good and usable connection.

It would appear that something in the way mstsc.exe is called is not working on x64, so it should be pretty easy to fix.
