Opening up the task bar and arrowing to another task that is open and hitting the "enter" key will sometimes allow me to bring back the cursor by clicking both left and right buttons on the mouse. Sometimes I have to continue to hit control-alt-delete before this remedy works. The majority of the time, it is at this point that any open windows just completely shut down. After this, the cursor may or may not be on the screen.
I have run multiple scans of spyware and virus ware which currently show no contaminants. My mouse does not have a scroll aspect to it. I have also run a check of the mouse driver through the IBM update site and it says this is functioning properly.
I have run out of ideas of other things to try short of buying a completely new mouse. Any suggestions will be most appreciated. Thanks so much. c
