I dissabled all ATI accelerator extensions and, knock on wood, so far no freezing. A little sluggish screen redraw but that´s OK. I tried all kinds of PlugInwindows and environments and moved them around while playing. The only thing that happend, and that was the case before as well, is that there are small audio-glitches while moving around.
