Portable ver. closes after switching privacy mark. Seen in 5.81, 5.82,..
Confirmed here, I've pointed the staff to this.
Thanks for raising this, I'm able to reproduce the issue, and I'll be happy to let our development team know about this to look into further.
In any event, it doesn't seem like it should be cause a large problem - it looks like it does indeed save the change in setting, so you can set the option how you want, as intended. But, of course, it should also not cause the program to close. :)
