There may be a race condition kind of bug during destroying form. So will it crash if the pclose cmds removed, eg
clear'' NB. clear base locale require 'graphics/gl2 api/gles' coinsert 'jgl2 jgles' testdlls=: 3 : 0 try. wd 'pc testopengl;minwh 10 10;cc g opengl' 'OpenGL OK.' catch. 'OpenGL create context failed. OpenGL not available.' end. ) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
