I work for a manufacturing company that uses Drafix 4, a CAD program designed for windows 95 but is still being used by 15 users to create layouts from custom libraries and heavy macro usage, so replacing with a current compatible software is not an option as AutoSketch (the new drafix - an Autodesk solution) does not support the libraries and macros. My problem is not that it doesnt work in XP but it hogs 100% of the CPU when the program is idle. My question is, is there any software utility out there that will detect a 100% load CPU condition and stop it before the CPU temp gets out of control. I have notified users to shut off the program when not in use but I have a handful of PC's that are overheating because of the load. Any suggestions?
