This happens quite frequently, if I come out of a game that has to be in a low resolution, like 1024x768 or 1280x720 tiles disappears, I have to go into the start menu and run the exe file for tiles to come back on the screen.  Tiles itself still shows on the side but every icon or link that is there doesn't show up hence haveing to run the exe file again for them to show up. This only happens after i've run old games with the lower resolutions, is there some sort of fix for this.
