Do you have an small > example to reproduce this? Indeed it is! Very odd then, as I'm quite sure about this. II have been tracing into the VBO code and there's no setVBO(true) anywhere (since I didn't know about it). It might be that I've been overwriting some memory or so then, but it seems a bit too coincidental that I've managed to corrupt only that bit and everything else is working ok.
I don't have a small example currently (our app is pretty big) but I'll do some debugging and look into it a bit more and see what happens. /Marcus ------------------------------------------------------------------------- Take Surveys.
