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.
