operating system: mac os X leopard, both on local index.html files or on
the web. both firefox and safari..

Once an exported OpenGL sketch is viewed via browser through generated
index.html (locally or online), the next time a different OpenGL sketch is
viewed via the same browser (without browser being restarted), browsers
tend to crash, or at least the second sketch doesn't work. JVM generates
this and similar errors on event handle call:
java.lang.RuntimeException: javax.media.opengl.GLException: Attempt to make
the same context current twice on thread

You can also observe the same problem on any openGL sketch uploaded in
openprocessing.org, below are two urls that you can see the issue repeating:
http://www.openprocessing.org/visuals/?visualID=173
http://www.openprocessing.org/visuals/?visualID=172

can you try this again with release 0146?

no response for 6 months, closing bug.
