What I believe is the problem is that I'm using a 3-box in a paned and the 3rd box is not allowed to reduce it's height to 0 which is what I need so it does not effect the others when the height is too small.(essentially the other boxes need to "rob" the 3rd one of it's height).

Any time I add any widget it seems to get a min height value of around 20 or 30 and will never reduce beyond that. In fact, I want the height to be infinite but visually it will never effect the height of the other boxes.

I guess I will have to some how programmatically make this work out or figure out some combination of widgets that might allow it to work?

[ Paned
[ Box 1]
[ Box 2]
[ Box 3]
]

Box 3 should have infinite virtual height but show 0 height for the other box heights.
