Taskbar Bug, Doesn't Bring Programs To Front

This is the second time I've gotten this bug, and it seems to occur roughly two weeks after a fresh install.

Long story short, I pin all of my favorite applications to the taskbar and when I click on a running program, I expect it to bring focus to that program (bring it to the front). Instead, it flashes yellow and the window that I want stays behind every other window. The only program that does not do this is Digsby for whatever reason.

Basically, the only way to see an existing window is to minimize all of the windows in front of it and only clicking on the window itself will give it focus. That's partly a lie, because I've discovered that a series of clicks on the taskbar icon will do it, namely: right click, left click, right click, left click. I don't want to have to do four clicks when one normally works.

I am running Windows 7 Professional 64-bit acquired through the MSDN program for students (Academic Alliance or something). I do know that I never had these issues in the beta with Ultimate edition.
