Could it just be a change from j807 to j902? j807 on my old computer where I have been
developing this app seems to work best for me. The old computer likely uses old graphics, too. So I could use some feedback about other other hardware as suggested next. Has anyone experimented to see where the turtle appears on their computer? If so, please tell me, and also please report your JVERSION and the 4 lines of system information at the bottom of the text provided after the Load. I show the 4 lines on computer A and computer B next below. Computer A GL_VERSION: 2.1 INTEL-10.0.51 GL_VENDOR: Intel Inc. GL_RENDERER: Intel HD Graphics 3000 OpenGL Engine GL_SHADING_LANGUAGE_VERSION: 1.20 Computer B GL_VERSION: 2.1 INTEL-14.7.8 GL_VENDOR: Intel Inc. GL_RENDERER: Intel(R) Iris(TM) Plus Graphics OpenGL Engine (1x6x8 (fused) LP GL_SHADING_LANGUAGE_VERSION: 1.20 -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
