Yeh, I did the uninstall and then reloaded the mouse but came up with the same result. There is one small detail here that I was told, by some other "experts",would not affect anything but I'm still wondering. This project started as a dead Compaq PIII. The motherboard was noticably dead. I put in a ASUS P2B motherboard. Everything except a spare parallel fit wonderfully. THe system came up, installed several drivers ( I don't recall what all they were). After another reboot the familiar windows 98 screen came up and all looked well. Until I tried to access the MY Computer icon and several others. THe icon would be highlighted, I'd double click and nothing. The mouse will pull up all the menus in the Task Bar, but when it comes time to do something--- it's gone. Man this is driving me nuts.
