Display problems on Tablet PC using Term

I am having a problem with my tablet PC (Toshiba Portege 3505). I am connection to a Win2K Terminal Session via RDP client, and when the resolution is set to FULL SCREEN and I switch from landscape position to portrait the display goes haywire. When I reduce the resolution in the TS, and use a window, it works okay. I have been researching this problem and believe it relates to the session only having certain display settings which are common for everyday monitor displays. I assume since the the session is handed down that the local OS/Display does not recognize the tab pc’s portrait resolution setting.

If any one has encountered this problem, let me know.
