Some Chrome users have reported a white screen when executing certain operations (AADL Import, Code-Gen-3, etc.). In order to resolve this in Chrome, open the java script console (on a Mac, command + option + j). In the console on the upper options bar select “>>” and then select “Application”. Then click the “Clear Site Data” button. This will require you to log back in to Tangram Pro but should resolve the White Screen.
