This is really aimed at squarely at Nicholas What's the status of the GUI clickthru (to 3d) problem, hover-behind-window and mouseover stuff - it's pretty hard to make complex 'naturally intuitive' GUIs right now. I applaud the Matrix, but would've preferred more complex events for Buttons and other controls. Why? I've built a File Browser control, but I don't want to release it because it's an arse to use. It pops up and all my 3d stuff gets the clicks, I can't (easily) get rid of the menu by detecting the mouseout and buttons incorrectly hovered by mouseovers in overlapping GUI's. Should I be waiting for a light at the end of the tunnel? Thx Shaun
