First reboot & shut down the box - try a different mouse and keyboard - if that does not work check your mouse properties in the control panel.
Do not get flustered this is an easy fix. If you are anything like me you spilled some water on the equipment and forgot!
I am having trouble trying to delete files with my mouse or with the delete key. My right click will not work...once I right click on a file or even my start button, everything closes. If I hightlight on a file and hit the delete key, everything closes. I have to drag any file to the trash can, but I can not use the "empty trash can" command either. I have to highlight any files in the trash can and click delete.
Also if I highligt a file and hit the delete key...everything closes. How can I get these functions back?
