Eek! This will be bad. The IK wants "all window drawing, including window borders" to be done in-process. Well, I disagree with the "window borders" part, but in any case, should someone hit this button, then the view won't redraw. And, if we go through with the "window borders" thing, then neither will it be able to reactivate, because, the thread will be asleep and won't hear the click. No, this sort of high-level control is best left to digigeeks who download programs like "processcontroller" -- wonderful apps -- to fudd around with their system and the like. Isaac
