I am not sure what happened because it worked the day before just fine. I cannot right click on ANY program on the taskbar. We used to be able to open more than one file- example in Word and Excel- but now can no longer do it because I cannot right click to open a new file. I tried two different mouses (mice?) thinking maybe the mouse was not working and neither one works. I tried restarting 3 times to no avail. What happened and how to correct it?
Thank you for helping me.
