How can I make the window showing
fps
action cpu
render cpu
other cpu

go away?

it actually wasn't a window in of itself.

more like a clear overlay in the top left corner of the Chessmaster window. It also showed how many rendered polygons there are along with some other statistics that changed as I played the game. Probably some one who helps to develop the GUI would know about it.

It was part of the chessmaster window, however the next time I started it up, it went away, so no big deal.

I just didn't know what keys I pressed to make it show up.
