Gui does not refresh


I have a weird problem on windows 7 with Blender 2.65
The GUI is not refreshing correctly,

For example, if I tap on “tab” to go into edit mode, the GUI show the mesh as if it was in object mode until I rotate the camera.

Another example: If I click on the view menu, nothing appears until I move the cursor up to where the menu should appear.

I tried to change the windows drawing settings, but it doe not fix the problem…

Any ideas ??

Update to latest graphics card drivers

I just did it, does not fix the problem.
By the way here the graphic chips ref : Intel® HD Graphics 3000

My bad, I update the driver from DELL, Intel has newer one. It works fine now.
