I need to be able to add the blank screen button on the bottom so that when a black screen comes up I can close it and it will go back to what I was doing, otherwise we get this white screensaver we can't get out of because there is no x in the corner to delete, and trying to close it the other way doesn't work either. Any help?
If it's actually a screensaver you should be able to exit by moving the mouse or pushing a key.
Otherwise try using Cntrl+Tab key to move between the different windows you have open.
