I have an older Dell Dimension 8100 that I have not used in a year. When I powered it up and plugged in the Mcrosoft WirelessIntellimouse (it is UsB compatible and I have always used the USB port install) that had been used with the system, the mouse cursor froze and can not move. A screen came up about whether or not I wanted to change form the Intelllimmouse. I could not get to the screen without a cursor. I couldn't even get to change the operation of the mouse over to the keyboard keys.
I would appreciate anyone'sa advise and assistance. Thank you!
