What I assume is going on is that Windows is looking to see where the mouse is connected. Although I don't have the details, there are a fair number of places to check, including an inport mouse, two serial ports, and a bus port. There is a requirement to meet timeout limits when checking for mouse presence, and apparently they are set fairly high for Windows (higher than in the MS mouse.sys, I suspect). -- Barry Press Internet: press@venice.sedd.trw.com
