That's b.s.! This is a valid bug. You closed it because I didn't reply with a screenshot quick enough? I've seen this reported at least a dozen other times, all closed. You just don't want to deal with actual issues.

What I wrote was entirely clear and says nothing about a crash. Why would I waste your time with non-important data?

We can reopen tickets. The crash report is necessary so we can see if something else may be causing the issue.
