This may be a red herring (I hope it is), but I seem to be able to crash the java VM quite consistently in Pure Immediate mode. With either 1.1.2 or 1.2alpha1 if I use the PureImmediate demonstration and keep resizing the window, then after a couple of dozen resizes, the VM GPFs on me (Windows NT4 sp5). I have stack traced it as much as I can on the java side, and it seems to die while performing the clear on the background. Does anyone have any ides as to what is causing this, as its not the kind of problem you can code around ;) Tim Darby - axarte ltd p.s. Regds the discussion going on about Java3D generally, I think Sun have done a great job so far, but the project would gain immensely if made open source or at least put into Sun's Community Source program =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
