After running simulations with Orcad Pspice V9.1 I can't shut down my laptop through the normal Start > Shut Down method. The error message can't shut down program "Dialog" appears. The only way to shut down my laptop PC is to turn the power off. I think (not sure) that the offending program may be "simsrvr.exe". I am using a Compaq Presario V2000 laptop PC running Windows XP home with SP3. Any suggestions?
