Thanks for all that Lab testing.
JVERSION Engine: j701/2011-01-10/11:25 build: Feb 6 2011 16:16:29 Library: 8.01.028 Qt IDE: 1.0.27/4.8.5 Platform: Darwin 64 Installer: j801 install InstallPath: /users/brian/j64-801 I cannot confirm your error in the Fuzzy Logic Lab (in j801, I have not installed j802). However, I do notice that some of the plots do not work intermittently. Upon repeating, they do work eventually. I also notice that the escape key does not dismiss the plots and that a click on the close button is required.
