Task Bar Thumbnail Bug Windows 7

[Daston]

Hey guys,

I am having a really annoying problem with the task bar in windows 7.

Normally when you have more than 1 of the same program open it will stack the icons on the task bar. When you hover your mouse over them thumbnails will appear which you can click on.

Now since last week mine has been doing the above, but as soon as I move the mouse just a mm the thumbnail will dissapear and then reappear. For example I can hover over say the the Chrome icon and have the thumbnails pop up, and then if I move my mouse across the icon the thumbnails appear and dissapear really fast constantly until I stop moving the mouse.

As soon as I go to click on them they dissapear completly so I am unable to maximise the window or open the program.

Alt+tab is also not working it just flashes the box on the screen for about half a second so I am unable to switch window that way.

The only way I have found to maximise the windows is to tile them and scroll through them with the mouse wheel (think its windows key + shift)

Any ideas would be fantastic!

Sounds like a registry error. I would try a repair using the install disc. Have you tried setting it to never combine in the taskbar properties, then reverting it back to always combine? It might fix it.
