My wife did something to our home computer (she doesn't know how) and asked if I could fix it. For the life of me, I have never seen this before (at least on a Windows box, i.e. XP SP2), and have looked everywhere I could think of to try to fix this. Failing that, I then look all over the net (including MS and Google) and have yet to find a solution, or anyone with this same problem. This is such a dumb (and simple) problem, it's driving me crazy, but here it is...

When you iconify (i.e. minimize) a window, it no longer shows up in the taskbar. It now shows up as a separate icon on the actual desktop (just above the task bar). It doesn't matter what type of application you're talking about (IE, Word, Outlook, Explorer, etc.), they all do the same thing. Anybody know how to fix this? Please help. Thanks.
