Alt-tab: window greyed out but does not move to background

Hi.

When I alt-tab between two windows, the previous window is greyed out but remains in the foreground.

This happens between windows of any program, whether it's Chrome, File Explorer, Firefox, Microsoft Word...

The new window is the active window, but it remains covered by the previous window.

The only way to switch between windows is for me to minimize the first window. Occasionally, alt-tab functions correctly and the previous window is sent to the background, and the new window appears in front of it.

Is there a solution to this?

I would try one of the free Alt Tab enhancement utilities. See if it does the same thing. Maybe you will get lucky and the 3rd party program won't have the bug. There should be many free ones on download sites like www.Softpedia.com www.Snapfiles.com SourceForge - Download, Develop and Publish Free Open Source Software and similar. Just make sure it supports Windows 8 or Ten so that it knows about the Start Screen.
