Bug: selecting a table in the tree causes tabs not to work

Steps to reproduce:
1) Open connection;
2) Expand tree;
3) click on a table in the tree;
4) clicking a tab (eg. query) causes a access violation.

If I click on the database name, then click the query tab, then click on a table name, it works fine.

This is a known proble in Wine, see issue #2227. Nothing I can do about that, unfortunately, as this is Wine specific.

Thanks, I only found it after updating to the latest beta (build 5.1.0.3584).

Probably also related: issue #2093. See the hint with "Wine MS Windows Compatibility Layer (Beta Release)".

From which one did you update, then? Probably there was some Wine incompatible code change in HeidiSQL, but I need to know which revision it was or at least roughly.

r3574 or so I think. Not 100% sure. I wonder if it's the update to the VirtualTree component?

Thanks, will check that. But no, cannot be the move to VT, as that was done much earlier.

The cause was most probably r3578. Could you please check again, after updating to r3586?

eh... better take r3587, please.

Just updated to r3590 and the issue has gone. Much appreciated!

Yes, a colleague at work already confirmed that. Means, Wine does not activate a tabsheet when its tab is hidden. This is different as on Windows so it could be named a Wine bug. On the other hand this is easy to work around in the application side, which I did in r3586.
