I've discovered some other significant (for me) change to the runtime
environment in the past few days. A traditional cascading menu (built
with the menu builder).... which worked fine yesterday during runtime...
no longer works today. The menu (which I dragged to the center of the
stack so it functions as a button with cascading selections), depresses
OK. The list of hierarchical selections show up OK. But any attempt to
actually make a selection fails.
At last I've found someone else who uses cascade menus!
Cascade menus were originally added as part of the old stack-based menu
system, which few people use anymore now that we can use the textual
contents of menu button as menu items without having to build a stack
for those.
But cascade menus remain very useful for another purpose, as flyout
menus. Adobe and many others place such menus at the upper-right of
their palettes, and they're useful in other contexts as well.
But unfortunately, the behavior of cascade menus differs from others in
that most menus let you click and release and the menu stays up until
you either select one of its items or click away from it, but cascade
menus only appear as long as the mouse is down.
Also, while most menu styles render their menus using OS routines,
cascade menus draw using the built-in emulated appearances, giving them
a non-standard look that compounds the non-standard behavior.
There are workarounds for this, but they're not straightforward to
implement and would certainly throw off the newcomer.
Jacque has noted this in the RQCC, and I've amended her request with
additional notes:

Richard, what do you use cascade menus for?
