I like unwrapping presents Christmas morning!
Nice effects, even though it's not SCREEN 0.
Want to bullet proof it? What I mean is, as coded, it fails if you pick a box like 46 but hold the left mouse button down for a few seconds. It will issue a message you clicked outside the box because it thinks you are clicking still on box 46. When you click OK, all subsequent clicks will be met with repeated looping outside the box error messages.
Check out the slight mouse revisions (see ----) dashes and the (2) remarked 'REMOVE' statements needed to fix the mouse held down issue.
Triggers on left mouse button depressed. Change mb value to = 2 for trigger on left mouse click released.
