So here's my next swing question: I've got a combo box with an action
listener. When you make a selection from the combo box, the action
listener fires off and does a bunch of stuff that takes a few seconds
to execute.

However! While the action listener is executing, the combo box does
NOT collapse. That is, I would expect it to first collapse (with the
new selection highlighted) and THEN fully executed the action
listener's code.

Is there a way to do this? I've been trying out various
implementations of the action listener to get it work, such as:

If you're going to do things that take a few seconds in the
EDT, then having the combo box stay open is a good way
to alert the user that some process is under way. Otherwise,
they will have no clue as to why the gui is frozen. You may
want to do anything that takes that long in another thread
though.
