Mouse Clicks
In the Sendkeys field that is mostly used for sending keypresses, special keys and macros there is also a limited facility to send mouse clicks.
The mouse click command consists simply of indicating which button to click (left or right) and the co-ordinates on the screen (x,y) to click. With the ability of windows to be on different parts of the screen often it is difficult to get a mouse click to always click the right co-ordinates, sometimes running an application maximized will help to guarantee that your mouse click command will always hit the right button or other control.-System Scheduler's Helpfile
I don't think I can use System Scheduler, because of "the co-ordinates on the screen". The various messages don't have the exact same size, so the buttons to click will not all show up at the same co-ordinate. Besides, I am using Dialog Move, and I really don't want to have to remember to leave my cursor at the exact same place at every shutdown. Furthermore, ClickOff is easy to learn how to use, but System Scheduler is difficult / tiresome to (not) figure out.
