Aero Peek and Alt-Tab Not Working Correctly

Haha! I can't believe other people have run into the same issue. I'm glad I'm not the only one!

Wow. I had the exact same problem. Unplugged my Plantronics USB headset and it fixed it too. Thanks so much for this!!!

I was also ahving this problem. I didnt have any headphones connected. decided to check the the speaker icon in the tray and it was flashing. when I clicked on it the volume was sitting there jumping.

I have touch vol control at the top of the keyboard (laptop), so i simply wiped over it to remove any dust. Viola. problem fixed.

I still have the same problem but none of this fixes are working. Nothing in any USB port, nothing in any mic or headphone jacks. I have a HP 8100 Elite desktop computer.

While looking for an answer to this I considered the fact that this might be a program causing the switcher to lose its "always on top" status or all programs getting "always on top" status.
If you have a Microsoft mouse ... and I know a lot of you must be saying "ahhhhhhh" right now ... when you plug that shit in, it has its own driver. That driver installs ipoint.exe. That's the little prick that's causing this. Kill it in your task manager and it should work right away. Uninstall Microsoft Intelllipoint software and kick it to the curb.
Mouse software is bound to mess with the state of windows in Windows.

I still have the same problem but none of this fixes are working. Nothing in any USB port, nothing in any mic or headphone jacks. I have a HP 8100 Elite desktop computer.

i had this issue, and unplugging the headphones fixed it. thank you for the tip.
