Thank you for your post.
I am unable to replicate the issue. This is what I have done:
1. Using FileMaker Pro Advanced 16.0.1 under Windows 10, I opened a database file that contains 20+ scripts.
2. I go into Scripts Workspace, and with no script selected, I double-click the third script.
3. With the script active, I maximize the Scripts Workspace, and I am still on the third script.
4. I select another script and close the third script.
Let me know what I am doing differently than you so I can replicate the crash.
I have just tried to replicate myself and it was working as expected however I thought (randomly) it may be triggered when the script workspace is a certain size to begin with. I attempted to resize the script workspace down manually to be very small and it locked up at that point.
This issue was raised by one of our team members a couple of weeks ago and I hadn't be able to replicate until today. If we have anymore info' to pass on then I'll post it here.
Thanks for your help!
