Ok try this hot key file out. I havn't tested it at all but it should work. It has ~2px of dead space around its outer edge. When your mouse is over the window it will tent the dead space black allowing you to see it. No this can't be turned off, its there so you can see it.. hello.. lol j/k
Any way let me know if it works and junk. Remember you CAN NOT access the contect menu for window settings unless you right click in dead space. No a blank key slot dosn't count as dead space. Outer edge only if you want to access the window, hotkey, my Moms number context menu.
Edit: adding the file might help /shrug
