I'm having very weird problem in my TS RDP connection,

I can copy and paste from my TS RDP out into my desktop (from any program into any program in my home workstation)

but somehow I cannot copy paste from my desktop into my TS RDP (from any program at all - it always remember the old content of the clipboard) ?

this is going through RDP session over Juniper SSL VPN into the Windows Server 2003 Terminal Server but obviously this is the same TS RDP application that is provided by Windows.

any help regarding this matter would be greatly appreciated.
