sorry for open up another subject, but after my troubles in getting the editor running within VirtualBox under Linux I tried to get the visionaire editor running on some older windows/mac hardware I had lying around.
Unfortunately all of my devices do have the infamous Intel 945M chipset - this also includes a Mac Mini (Late 2007).
The "crash behavior" is always the same (and applies to Windows as well as MacOS 10.7):
The editors starts up, I load the example game and then the editor crashes as soon as graphics (e.g. scene editor) should be displayed.
After that the visionaire log says "Open GL 2.0 not supported.".
For curiosity I fired up the Deponia Demo and for my BIG surprise the Game was running fine.
So it looks like it's not the engine, but the editor itself which keep crashing.
Just to make sure that OpenGL in general is working I fired up some Games (GLTron, Tux Racer) and they were working fine.
Same applies to DirectX/D3D Games ... I tried 3DMark03 ... and it worked (slow but working).
So there definitely seems to be some bug in the 4.1/4.2 editor (I didn't had the chance to check earlier versions)
