I'm already adjusting the height of the stack and placing the

Moreover, AFAIK it's not possible anyway, since stacks popped up
with the popup command only trap one mouse click and then close --
regardless of what was clicked on. Given their original purpose, to
hold only menu item buttons, that makes sense. But attempting
manipulate controls like scrollbars will be an exercise in
frustration: click on the scrollbar to drag it, and the window goes
away.
Yes, I thought this was the basic problem.
You could work around that by not using the popup command, but
instead using a simple borderless palette and watching events
carefully (very carefully; popup controls are simple for users
because whatever system that implements them is working hard to
deliver that seeling seamlessness).
Much better to see this fixed.
I agree. I'm not going to try a complex work-around for this.
As for your gallery, I wonder if it might make sense to have only a
subset of options available, with an item for "More..." which opens
a dialog with a scrolling region to show all of them. This may even
be a benefit to the end user, since it starts them off with with a
focused subset. Of course the usefulness of that depends on a lot
of things I don't know about your app; maybe something to consider,
maybe not.
I'll probably run with something like that.
Hmmmm. Can you scroll a group with the scrollwheel using a rawkeydown
handler if the group has no scrollbar? With or without a frontscript?
That at least would *look* like a regular menu.
Yep: rawKeyDown 65308 is "down" and 65309 is "up".
Yes, I put this in the stack script and it works fine with the stack
at toplevel. What I may do is have a "more..." menuitem/button at the
bottom of the popup list when the list gets long, and use that to
toplevel the stack so it can be scrolled.
Thanks for all of your suggestions, everyone.
