Application freeze on dialog close [Mac]

[Kevin Rushforth]

I haven't seen anything exactly like this, but it might be related to a 
system setting or a terminal setting (if the app is launched from a 
terminal) on the affected systems. You might check is whether the 
"Secure Keyboard Entry" setting in the Terminal is enabled on the 
affected macOS systems. If it is, you should see a timeout warning 
message when starting the application as  reported in JDK [1]. It seems 
possible that this setting might also cause something like you describe. 
If that's not the problem, then it could be some other system setting.
