OK not every time, but in some circumstances it happens a little to much. The circumstances are viewing 3D openGL window with render background, and render background is a picture. I got this issue some time ago, on my MacPro (with nvidia 7300GT) but I thought the file was corrupted, and I didn't have much time to investigate.
Now I had the same problem on my MacBook Pro with another file. Because it was repeating the same issue, I tried to investigate a bit more. I cleaned preferences, I joined my file on a new one from Archicad 12 template, I resized the image, but the issue remained.
After that, I tried the same file on two iMacs (one with ATI 2400HD and one with 2600HD), and all worked fine. I opened 3D openGL more times, I changed the backgrund picture, without any crash. Now I'm on my MacPro, and I tried the same file I tried on iMacs, and... Boom! Open it, open 3D open GL window, and Archicad crashes.
How an hassle, how much time I spent the previous time I needed to adjust the view for a simple render on a picture! A little job I should do in little time...
OK, is there anybody else there, that had the same issue?!
