Yes, thank you, I did try that, but it didn't help ... what did help, which I've just found out: installed the latest driverpackage for the Matrox G400, and the problem seems over for now (touch wood ...); but now I see memory is filling up rapidly upon switching the panels, which it did before, but before reaching the 'low virtual memory' threshold, the application would crash. Now, I have some runtime allocation of objects (ouch), but not nearly as much as I see it fill up; I remember the Java3D-buglist mentioning some memory leakage problems ...
