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.

Wow! I never saw that happen before! If you click that like a normal person it worked fine BUT if for some reason you are extra slow on the release (and I guess we do get that way eventually) that becomes an app from HELL! After a long click the first message is correct BUT it just thinks you selected and clicked and selected and clicked over and over again, yikes!
So all that was changed was the MouseZone% Routine, you have to add a loop to that? I have to study that change, seems like there would be something simpler to fix that.
Thankyou for alerting me to this and providing a solution.

Also, Mark, glad I could help. The DO/LOOP is self-exiting after a mouse cycle is completd. It is required to measure all states: 1 = Depress, -1 = Held Down, 2 = Released, 0 = Cycle completed. Yes, you could construct another method to achieve the same results but I'm not sure it would be simpiler and universally applicable.

@Bplus
very nice multiple button menu application!
We can say that Pete is a good debugger! He has catched the queue of mouse input bug in a glance!
@Pete
my 2nd example of menu is already a sukerfish menu but it uses a voice/item of menu to go back...
now here I post a version using as control the click out of the menu area...
It is still in working both for modularizing menu management both for getting a better mouse input control...
for now you can see menu flickering if you continue to click on the menu item for submenu (Menu2 and Menu3)!
I think that I need to use an array for menu data for a simpler management of the menu system and a more accurate gathering of the mouse input.
I'll try to do these improvements as soon as I have more time...
