May be my mind is too small, but if this is true, then Quantum Mechanics is flawed. But I have to wonder what the quantum definition of “at once” is. :-) Bob S On Mar 2, 2015, at 13:07 , stgoldb...@aol.com wrote: In quantum mechanics something can be in more than one

Re: Fwd: Quantum tunneling in LiveCode

While on the subject of out-of-the-normal message paths, I came across another one a couple of months ago. openControl messages are sent to the highest level group and then DOWN to any of it's child groups which seems the opposite of the normal message direction. It gets more interesting though.

Re: Fwd: Quantum tunneling in LiveCode

Thanks for that explanation Richard. I finally get the difference between sharedBehavior and backgroundBehavior. Seems like sharedBehavior is the one to use for everything except old HC stacks. On Tue, Mar 3, 2015, 7:14 AM Richard Gaskin wrote: > Stephen Goldberg wrote: > > > I think the bottom

Quantum tunneling in LiveCode

In quantum mechanics something can be in more than one place at once. A paradox of sorts seems to occur in the message chain with groups in LiveCode. Try this: 1. Place a button on a card. 2. Make the button a group. Set the group's backgroundBehavior to true. 3. Place the following script
