It's fixed now for me. For some reason Desktop Windows Manager was disabled on my machine. I forget exactly how I discovered this but I think I recalculated the Aero score and when it finished it brought up a troubleshooting dialog box which I then executed.

Once I enabled the Desktop Windows Manager and rebooted for good measure the problem went away. Seems to be working fine in Aero and non-Aero mode.

Thanks for your help.
