Strange Internet Explorer question

Let’s see if I can explain this so it makes sense.

I am having trouble maximizing Internet Explorer. When I maximize other apps from the taskbar, in order to get Explorer to open, I have to minimize everything that is “in front” of Explorer. When I maximize Explorer it will be “behind” everything else that is running.

I have never seen anything like this and this is the first time it has happened on this machine.

How can I get it to go back to normal. It is a real pain minimizing everything to get to Explorer.

Thanks

Have you tried rebooting? I recently had my machine on for 19 days and it started acting all funny like this.
