dear kenneth,

there is no bug in gl4java - for sure ;-)

because there is no limitation to use "glXGetCurrentContext" !

(btw: there is no more "enableAWTThreadRendering" ;-)

i do now collect the calls of "glXGetCurrentContext"
and do comment them out temporarey, till NVidia has bugfixed their
release ..

there are also some more offscreen renderer bugs within NVidia's driver,
i do _not_ workaround now .. (in a lack of interest)

well, i am also not interesting in doing much workaround work
for their drivers and their bugs .. so i just do a checkin in 
some minutes .. and we may see what happens ..

but, of course, thanxs a lot for your attention ..

later, sven
