Sounds to me that you are making a lot of work for yourself.

I don't really understand why you are keen to subvert the normal
behaviour of minimise. The OS is only doing what the user surely expects
- Hiding the window off-screen at very distant co-ordinates and making it
recallable via the taskbar.

Since it is the OS, not Revolution, that reacts to the minimise event,
I'd expect it would be frustrating to try to circumvent it. Your best
bet in that case might be to have no title bar (decorations empty) and
instead construct a fake title bar of your own (using graphics) that
implement the behaviour you prefer. But you'll have to implement your
own window drag, close etc. as needed.

When I want to collapse a window I just programatically change its size
so that the components I want to hide are no longer visible. Generally I
would store the expanded / collapsed sizes in a custom property of the
stack, and have a small button of my own to grow/shrink the window.

In your case you might also need to have your script resize or
reposition some controls in the window, but this is quite easy to
accomplish, especially if there are only one or two of them.
