Forcing Program In XP To Use 1 Core

[ZXSpectrum]

Is there a way to do this from adding a switch in the shortcut or registry?

I have a program (Navisworks Jetstream V5) That will only do a 3D Walkthrough correctly and smoothly if you go into the task manager, go to the running program, right click then set affinity and disable the second CPU (Second Core)... Is there a way to get this to do it automatically when the program starts? When the second CPU is enabled the walkthrough flickers rapidly and stutters constantly...

Thanks

Have you got any links matey? I have been searching for a while now but there does not appear to be any options to enable/disable cores when creating or modifying a shortcut.
