Windows 7 Problem with Recent document in Start menu

[Flame113]

Normally when i move my mouse over an item like Getting started or Sticky Notes, it will list out a list of items. But it's not working now :-s I don't remember what I've changed.
Go to Taskbar and Start menu properties and I have both privacy checkboxs checked

Pls help me! Thank you very much

Possible fix.. Click "Start" and type and enter "ap" to enter the appearance menu.
Click "best performance" then go back to "Let Windows choose.."

Thanks for your quick reply but it doesn't work.
I think this problem occurred after I ran iolo System mechanic Advanced system settings (tried to add Open windows command here...)

Mouse-over errors seem to be connected to the Aero feature. There is an aero trouble shooter under the troubleshooter program. It may help.
