getting doubleclick on a menu-popping control

[Bob]

My control pops a menu (below, not directly under, the pointer) OnMouseDown,
and, probably because of the loss of focus, OnDoubleClick doesn't fire any
more. Is there a way to get doubleclick back without some ugly workaround?

TIA,
Bob

Why don't you fix it so that the MouseDown only pops the menu on a right
click? That will allow a left double click to trigger the other event you
desire.

Will that work for you?

No, that's not acceptable. This is a button that must function like the menu
icon at the top left-hand corner of a windows form. You left-click it, you
get a menu. You double left-click it, it closes the form.
