I have seen several posts about win 2k pro not being happy with a serial mouse and tried all those answers. But none have really described my problem well. Not only do I not have a mouse ... I don't have a mouse cursor. I don't have a mouse option in device manager. It is like this system was made to operate without a mouse at all. Please dear god ... there must be someone out there who can help! I am thinking the next thing to do is to see if dropping the stupid thing a few hundred feet will fix the system at all.
