Still crashing when opening a devices settings...

I read that this bug has been fixed but yet it still does it in Beta8. It’s really annoying to have to improperly shut the program down and most of the time have to reboot the server in order for it to function properly again for 20 mins. Is there any suggestion on how to correct this or is it still in development? Other than that, this is by far the best “free” NMS software I have come across.

Thanks.
