When I navigate within Explorer, highlight a file, and right-click, the menu that usually pops up (open, copy, paste, delete, etc.) does not show up and Explorer shuts itself down and I receive a prompt to restore my active desktop. The issue only seems to happen with files and my Quick Launch Toolbar, and these right-click menus work fine in my other programs such as Word, Excel, and Internet Explorer. Keyboard commands do not work in Explorer either...for example, if i highlight a file for deletion and I hit "delete", Explorer shuts down again. The only key command that seems to work is Ctrl-A to highlight everything. Other than that, all others fail.
I originally attributed it to Mozilla Firefox and have scanned for the Blaster virus, but it is not there. I have also run a number of virus scans and checks for system errors in addition to updating Internet Explorer and Windows. This problem originally occurred when I tried to transfer photos from a digital camera to my laptop via USB, but I have been doing that for a number of months problem free. I uninstalled the USB driver but the issue is still there.
My laptop has been on a shared home network with a desktop for almost a year now. The desktop has no problems (but it does have access to one shared folder from the laptop). I disconnected from the network (and the Internet) and tried it again, however nothing seems to help it. Hopefully that gives you a fairly good idea of the situation.
Any suggestions you have would be greatly appreciated.
