Yes, I thought this was the basic problem.

I agree. I'm not going to try a complex work-around for this.

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.
