Descriptive Problem Summary:

(Test project sent in private demonstrating the problem. click through character creation until you get to the name character bit. There's a screen widget there that puts an input on the screen over the screen object. My math for calculating its position is pretty correct.)

on-resize messages aren't sent when "tearing off" a window.

1) Maximize the window
2) Click the input box. It should be in the right spot.
3) Drag the title bar of the window until it goes back to its normal size.
4) Click the input box again. It is no longer in the right spot, because a resize message was never received.
