------- Additional Comments From thunderbird2k@gmx.net 2007-28-07 15:26 ------- It seems that this program is very critical to the pixelformats it receives. We only have a single pixelformat for window rendering. At the moment I'm offering this main window format and all float (offscreen) formats. I could mark some other standard pixelformats as offscreen only. That would fix this program.
