RDC sessions to Win 7 terminate on CTR and arrow keys

I am trying to do a Remote Desktop Connection (RDC) from my Powerbook G4 (OSX 10.开发者_StackOverflow中文版5.8) to a Windows 7 machine. The connection is established without any issues and the remote destop is displayed properly. However, hitting CTR or one of the arrow keys terminates the RDC session which is very annoying as you can imagine.

Any ideas on how to fix this?

Fixed by downgrading to RDC 1.0.3 ( http://download.microsoft.com/download/4/9/6/4963025f-1731-4a9e-a9e6-8f6ab6ac4625/RDC103EN.bin )
