OK, I was able to almost hunt down the problem. When I open a 
B3DSceneExplorerMorph I can activate hardware acceleration. When I grap the 
morph and move it around, acceleration is disabled instantaneously. And I 
can't switch it on again. The reason seems to be that in B3DSceneMorph>> 
outOfWorld: the method suspendAcceleration is called. But the corresponding 
method intoWorld: where the setting is reversed is never called.
