hmm, which gfx-card do you have? (which driver?) does it support openGL-2.0?

anyhow, i have added a new object [GEMglReportError], which you can  
use to find the source even more easily. just put it into the  
gemchain, and it will output a non-0 value to it's right output  
whenever it encounters an error (probably use [change]->[print])

i get ONE error on _some_ machines; but i don't see it here on w32  
(though i think the same machine on linux does produce this error)

not directly.
but once you have generated thousands of these, the buffer of the  
pd-console will fill up and eventually eat all your memory.
a quick workaround is to run pd with "-stderr" which is faster.
