I have been working on WBC-4 on my mac. It has two screens and when I had the instructor check the code he said there was an error. I downloaded the zip file I sent him to my mac at home and it worked fine. Knowing that he uses a windows system I spun up a win7 VM and sure enough, the scenario opens off screen. Holding down the shift key and right clicking to maximize gives me a visible window but that's not a solution. I also unzipped the same file on my Ubuntu laptop and it also opened properly. Has anyone had this type of issue? My solution was to take the .java files copy into a pristine WBC-4 scenario directory on the windows system and it's fine. Since I'd like to just create my zip files for homework on my mac I would REALLY like to know what the fix is.

Hi, I tried to implement a javaFX class which extends an Application. This class runs without problems in BlueJ, but if I try to use this class as an "other class" in Greenfoot and start the javaFX Application greenfoot produces an error, also the Application Window is shown correctly. Greenfoot stops working and the Debugger shows an sun.misc.Unsafe.park. I have to restart Greenfoot to go on working. Do you have any solutions for my problem? Thanks a lot for your help.
