When the screensaver kicks in and YoWindows runs, if you move the mouse, YoWindow does an Exit (assuming you have the "Close screensaver on mouse move" option enabled).
When I run YoWindow manually, I noticed that if I use the X in the top right corner to close the program, it just minimizes down to the system tray. I do NOT like this :!: Instead, I need to click on the Program menu and choose Exit -OR- hit the Esc key.
Hitting the Esc key is not a problem, but I would also like to see an option to allow the X button (in the top right corner of the Window) to actually perform an Exit (like the Esc key) or NOT minimize the program to the system tray, however you would like to word it.

Thanks in advance and keep up the great work.
