Can´t disconnect a host

When I disconnect a host, HeidiSQL crashes (reproducible). "Continue Application" does not work.

I cannot reproduce that here. Can you describe more detailed: Which tab was open (i guess "Datatabase"?), was there a second active connection or did the session manager pop up?

The "Databases" tab was open.

Hmm, perhaps you have to do this:
I have a stored connection to an IP-address. This connection was open. I then opened the session-dialog, edited the stored connection to another IP an clicked OK. HeidiSQL asked to save the changes and I clicked "no".
There were then two open connections to different hosts started from the same stored connection. (Also, there were a few additional connections "active" in the tree, if this is important).
Then I closed HeidiSQL (after a few operations on that connection), started again (next day), clicked the second (unstored) connection in the tree and clicked disconnect -> Error.

Hope this helps

I'm sorry, I'm not able to reproduce this crash here, even by following exactly your reproduction recipe. Can you reproduce that?

Yes, I can

In that case the above reproduction recipe is probably missing some detail.

Hmm, perhaps it´s a detail I don´t pull together with the crash (?)
Is there anything I can try/test?
