Windows 7: Windows Taskbar jump lists, thumbnails not working

I was given a new Windows 7 laptop at work today. Came with Hope Premium. Performed an Anytime Upgrade to Professional.

I've discovered that the taskbar is not working properly, and I don't know if it's a problem with the taskbar, or aero.

1. Can't move/rearrange shortcuts on the taskbar, even when the taskbar is NOT locked.

2. Left-click & Drag-up for Jump Lists does not work properly. The jump list appears, but as soon as I move the cursor off the shortcut, the jump list disappears. (Right-click on short cut does make jump list work)

3. When more than one instance of a program is running (ie. Windows Explorer), and I hover over the shortcut on the taskbar to see the open window thumbnails, Ican not move the cursor to select the window I want. Instead, like with jump lists, as soon as I move the cursor off the shortcut, the thumbnails disappear.

I have tried rebooting, and hard booting.



Has anyone else had a similar problem? Has anyone seen a solution?

I found the solution on these forums. Guess I just needed to do a better job of searching. It appears to be specific to Dell computers (including Alienware, which is owned by Dell now).

Solution is in this thread: Taskbar thumbnail preview disappears quickly
