PC Studio viewing issue- Windows 7 hardware accelleration

We are running Windows 7 64 bit and when I try to use PC Studio it is jumping all over the place.  making it almost impossible to work.  In XP I would just turn down hardware acceration but with the Wind 7 driver this privledge is greyed out.  I have tried changing the compatibility for this app down to Wind XP but the graphics are still jumpy.  Any suggestions??
