Bill, Both my browsers seem to support webgl according to http://doesmybrowsersupportwebgl.com . Am I supposed to do more than run the jdemo.ijs in jhs? I did this by selecting "run" or "run display" from within the tab created by jijs and named "jdemo.ijs".
Thanks, -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
