Windows 7: Black Rectangle appears on desktop after locking PC

Black Rectangle appears on desktop after locking PC

Hi guys
recently I've noticed if i lock my pc and then unlock when i come back to my workstation, a dark grey square with inactive arrows appears in the top left of the screen, i cant move it, click on it or close it! It doesn't seem to have any "always on top" setting as i can put any program or explorer window above it and it stays happily on the desktop behind the window.
A restart of the PC removes it but that's not always practical to do
Have a look at the screenshot attached and let me know what you think it could be and how i can remove it!
Thanks

It would appear an tray application or some background app you have is not loading properly when you unlock the machine. It's possible the act of locking it actually causes the problem with the specific program in question.
If it happens all the time I would guess it's something in your startup programs.

If you go to the search box and type msconfig and hit enter then go over to the startup tab, could you screen and post that ... just the one tab.

hi maguscreed
its a pretty long list of things, the box doesnt come up all the time, ive narrowed it down to appearing just when i lock then unlock the pc
ive put a screengrab in the attachment but as you can see, it doesnt even cover half of the startup items!

All I can gather from that is that you have atheros devices.
Their drivers are known to cause problems because of power plans and other things like log off/ locking.
If at all possible you may want to make sure what you have for your atheros device is the latest available.
