ScriptUI CS6 on Mac: listbox crashes app?

[Silly-V]

I have a very unique problem which I would have never known about because I do not have CS6 on the Mac: this very simple dialog seems to crash the entire application after it is dismissed. The only special thing about it that I can assume is the presence of a multi-column listbox with headers? It definitely works in CS5 and CC on Mac and Windows, and, as far as I am aware, on all versions on all Windows. This seemed so unlikely, and I am as happy about this being brought to my attention as I am dismayed that it's a real issue! How weird, what can be changed in this code to make it not crash?

I have no idea if this is correct as I don't have a mac to test it.

my thought is that it could be due to relying on the result provided by .show().

here I have replace that with .onClick and .onClose to get value and pass it to a function.

not sure it will make a difference but worth a shot.

Sadly, my CS6 Mac crashes with that script alteration…

bugger

So this is not just a regular listbox, but one with headers and multiple columns, and it's using a re-defined variable to assign properties to the list items, anything and everything could be suspect with this case.

[Silly-V]

It appears that it's a bug which centers on multiple columns, so for Mac CS6, I think I'll make it put all the info into a single column and try to make it look as pretty as possible.

Sorry, I've had a few issues with an engraving machine here and so have not had time to do any testing.

Now I have quite a backlog and can't see myself getting time to sit on the mac till next week.

have you seen that Kahrel has updated his scriptUI document this month.

I've not had a chance to read all the updates but you may find some insight there.
