Just start SwingSet example that comes with Swing
preview code, select one of the combo boxes so that
the popup list is shown, and then move the frame
by selecting the title bar and dragging it. The
combo box will move (being a component), while
the popup window (being a window) will stay :-).
This happens on other platforms as well.

You should track the focus and hide the popup
as soon as some other window receives it (check
the behaviour of Windows combo box).

On my Solaris system, both pulldown menus and combo box popup lists can become
disjoint from the main window.

Run the SwingSet demo - make sure there is another window behind the SwingSet
window.
Post the File menu by clicking on File - leave the menu up.
Click on the window behind the SwingSet window to bring it to the front.
The posted File menu stays on top of all windows.

The same thing happens with the popup lists in the combo boxes.
In addition, if you move the SwingSet window, the popup list window does not
move with it.

It would also be nice if the menus could be unposted by clicking anywhere on the
screen as with native menus, but I can appreciate the difficulty with that.
