help fix javax.media.opengl.GLException: Error making context current

[Ronald Klop]

Hi,

A little googling on 'javax.media.opengl.GLException: Error making context  
current' gives a lot of pages about the same error people are having  
(mainly on Linux).
It looks like it depends a lot on versions of  
OS/drivers/libraries/graphics card, etc.
And also about how robust programs are programmed related to small  
differences in threading+opengl of the OS/java implementation.

So it is quite a hard question to answer AFAIK except when somebody has  
seen exact your problem in the past and solved it.

Ronald.
