the problem 9

for best viewing, go Large. didn't even realize it was the 9th image, so funny.

this seems to be an issue throughout windows operating systems when it hangs, sometimes to the point where one is unable to move the mouse/get out of it, but regularly it simply causes a short period where when you drag a window around it creates "tracers" that trail behind it where the desktop should be. i believe its corrected by restarting explorer.exe
