Wireframe without OpenGL works fine now. My house project no longer crashes when selecting the cylinder and cube for the door. However, droping my group is a bit unexpected, as it tries to drop the cylinder to the ground too - instead of maintaining the relative distance of the objects within the group. If I wanted the cylinder to drop, I'd select it by itself. Beside the missing branches and interface redraw issues, there is also a bit of an issue with rendering a full screen image on Mac. It doesn't seem possible to do anything with such an image after it's rendered. Actually you just have to push Escape before the menus return, but it's not obvious. And cancelling with Escape doesn't bring the menus back either - have to press Escape twice more (in 4.04 too btw). If you go back to the scene with F8 - getting back to the 3D scenes becomes difficult as F8/Esc don't do it. - n8
