Hi

rgl crashes my R session, when resizing the rgl graphic window.

I am using Ubuntu Maversick, with dual monitor setup. If I disconnect
one monitor, I can resize it "a little bit", but it still craches if I
enlarge it to much.

I assume that the problem has to do with allocated graphic memory in the
kernel, but why is R crashing completely, and not evn giving the usual
crash options?

Cheers,

Rainer
