Context Menus - the look of the thing

Yes, the button contains a classic 'menuPick' script. In a test rig, it works fine as it is.

I just made the thing work. I THINK I did this by ensuring that the button was in the hierarchy of the stack that was invoking it with a 'popup' script: previously I had tried to put the button in a completely different mainstack. My program had no difficulty in accessing this button, for example an 'exists' query in the calling script found the button correctly - but it turns out (I now think) that popups are unusual beasts with their own peculiar habits.

I rather hope to have a short chat about this with someone at the conference.

Thanks

Graham

Basically I have the button menu in an obscure card in a mainstack somewhere, and the mouseDowns can easily be shown to be reaching this stack and even this button, but the popup doesn't pop up. My mouseDown handler looks like this

I can set a breakpoint in the mouseDown handler at the line immediately above the 'popup' line, and the code stops at that point, but with or without the breakpoint, no popup. I just can't see what I'm doing wrong, tho it's probably blindingly obvious. Sadly one can't breakpoint the actual popup action, only the script of the button after the popup action has taken place.
