Taskbar icons not working

You have your video card setup to run in multiple monitor mode.

Change the display preferences to run in single monitor mode.

If you actually plugged in another monitor into the second video card port, you would see the output that was captured in your screen shot.

This is a configuration issue, which is controlled by the end user.

A quick way to check this is to hit Win+P. If an alt-tab looking window comes up with "Extend" highlighted just switch it over to "Duplicate".

wow!!! I've had this problem in various forms for months. the win+P did the trick. It seems to have corrected many problems. thanks!!!!
