DM: Hi, Vilius. Looks like the bug that I filed here:
https://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=4520
. I hadn't thought about a difference of how one enters a folder (I
usually always do so using the keyboard), but you can see from the
comments on the bug report that I had a variety of hypotheses on what
was causing it, but even the final one I 'settled' on didn't
consistently produce the bug. As you may already be aware, I'm guessing
it's caused by the switch to GTK3, but I don't know for sure where the
problem is or how to fix it. HTH, ---Dustin
