Yeah this is definitely a RT thing, my 9600 is on stock clocks and completely stable with WHQL drivers. If i close the program and run it again it's fine, i'll try to get a pic of the next time it happens. Even though the box goes black / see through, when i move my mouse cursor over the areas where the fields of text are the cursor changes accordingly. Really strange! It's definitely after extended periods of time being minimized.
