Thanks Ken, but I don't think that's the way to go .... it might be 
possible to do it that way, but Martin's suggestion looks like the 
easier approach.

I wasn't. I remembered it, but somehow failed to make the connection to 
using it in this case. The docs even say

so that's what I'm doing. I now have a regular button, with a mouseDown 
handler which decides whether to pop-up or not.

The only odd thing is that when I depress the mouse button, I get a 
mouseDown to my button, and when it does the "popup" I immediately get a 
"mouseUp" to my main button - even though the mouse button is still 
depressed. When the mouse button is released, that is taken by the popup 
button, and therefore doesn't go to the original button. So I guess this 
ensures that the mouseDown and mouseUp events stay symmetric- but it was 
a surprise.

I would have added this to Web Notes entry or "popup", but that option 
isn't available (grayed out). I remember this was mentioned a while ago, 
but don't remember any conclusion - is adding to web notes disabled ??
