<br>
I think I submitted a refactor of the INDI Control Panel in KStars<br>
that should fix such crash-on-disconnection issues. This commit has<br>
the fix: 678c5e360c7651060c65133ed97b074c0b24bc40<br>
<br>
However, we must thoroughly test KStars now for stability issues.<br>
Robert reported crashes on the MacOS client with INDI, so this needs<br>
to be investigated. The due date for 3.5.5 was planned for September<br>
6th (Yesterday) but I really think we should delay perhaps for a few<br>
days until we ensure stability issues are addressed. Hopefully more<br>
users would try the beta to report back. Keep using KStars with *real*<br>
equipment under real conditions to catch some of these elusive bugs.<br>
<br>
