I Have Uninstalled Version 1.1 and Installed Version 1.15, thank you for fixing many of the bugs. I still have some problems with Fast User Switching in XP. I keep getting an error message regarding being unable to load Pguard.dat (despite have full permissions for access). Gavin's trick of Disabling Protection and Exiting Process Guard doesn't seem to solve this. It does allow me to reload Process Guard after swapping users, but the other problem becomes apparent. This problem is that in the new user's account, when I get Process Guard loaded manually, I can exit and close Process Guard without any "Human Intervention" code being requested or required. The DiamondCS Process Guard is Started and set to Automatic in both cases.
