Let me add a possible answer: Do you think it might be worthwile to try compiling Paraview with Mesa on Windows (version 7)? As it seems that the "native" OpenGL support is not really stable with the latest driver - is there a chance that going through Mesa 3D would improve the situation? Or is it even impossible, so I should better not even bother trying?
Thanks for any helpful hint! I mean: It is possible to do some limited working with a "ticklish software" that tends to crash regularly (first of all: always save everything immediately!), but it is not really so much fun...
