------- Additional Comments From oliver_stieber@yahoo.co.uk 2005-06-10 08:44 ------- I think that we should have some code in either X11DRV or ddraw /d3d that overloads the winproc for the window and manages those kind of events. This is needed for scaling the surfaces when the window is resized, so there's no reason it couldn't be done for ALT+TAB or ungrabbing.
Personally I don't like DXGrab in desktop mode, because it makes desktop mode pointless.
