I thought that you all might be interested to know that I have been testing Process Tamer on Windows Vista. There are many problems with Vista and changing process priority, even using task manager, the priority will snap back to its 'default' an a few minutes... and forcing a 'preferred' priority is just not reliable. Intrestingly enough, process tamer seems to work just fine!!! The only problem I am finding, is the 'configuration utility' which looses its brains after a couple of uses, but re-installing gets it up and operational easily... I dont normally make many changes to the config, so this is not a real hardship. I run VMWARE 6, so boosting priorities is a major issue for me, and so far, ProcessTamer is the only package I have found, including commercial packages that works properly with Vista ... Well done guys!
