Windows 7 shortcuts not working

[RupertT]

Some of my Windows 7 keyboard shortcuts are not working, such as Alt/Prt Scn does not take an image snapshot of the open window, or Ctl/WinLogo/Tab does not cycle through active program in Aero Flip 3-D or otherwise.

Alt/Prt Scn sends the image to the clipboard, so while nothing appears to happen the file is sitting there waiting to be pasted into a document or a photo edditing program.
As to second part, it works on mine so I can't say why not on yours.
Maybe if you supplied some specs of your system and which version of W7, someone may be be able to help.

Its not Ctl/WinLogo/Tab it is Winlogo/Tab only, and it only works if Aero is enabled.
