If you have terminal services running on Windows XP Tablet PC Edition, and you log on to a terminal server session, any program that is configured to start during terminal server session startup may not start if that program causes the the pen input utility, Wisptis.exe, to start.
This behavior will occur if you log off and attempt to log on again. The program that causes Wisptis.exe to start cannot start because Wisptis.exe is still resident in memory.
To workaround this behavior, you must configure Wisptis.exe to close after each terminal server session:
1. Open a CMD.EXE window.
2. Type the following command and press Enter:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs" /V wisptis.exe /T REG_DWORD /F /D 0
