Eric,
This is a bit off topic (more general Swing/AWT stuff) but if it helps...
You need to give a little more detail for what this is for. The problem is
that when a window isn't visible, It doesn't have the focus from the
keyboard. So no keyevents ever get to it.
So something needs to be a the key listener to evoke the window you want the
following code does what you want sort of.... Once the window in question is
open, it can listen for it's own key events to close it.
In my example the smaller window f2 will listen for the keyPressed... and
then the larger window will listen for the keyReleased. The larger window
would be the window that stays open only as long as you hold down alt-e.
