Really? I could have sworn you indicated that very thing for someone
else's issue. OK, I'll take your word for it and will try it.

That would solve a lot of problems.

YES! That's it. And CRIPES! I may need a new brain. Or there's a
problem in the doc somewhere. When I was researching this I didn't see
Action documented as being available for Menus. However I just went
back and sure enough, there it is.

I will get to testing it. And I will apologise to the OP as well. Thank you.
