Clicking on Query tab closes the tab (random error)

Greetings

Just upgraded to v12 and I noticed a strange behavior - not every time but quite often, clicking on a Query tab, will close the tab (not hitting the "X")

Thanks

:S:

You have likely double-clicked a tab, which then closes the tab. You can disable that behaviour in the context menu:

stupid mouse, must be bouncing ... ok, thanks Ansgar, makes sense

Hi, I would like to disable the double click closing a tab option, I keep accidentally closing tabs... However, when I right-click a tab, I don't have the same context menu as you. Mine only displays New, Close and Rename Query Tab. I have HeidiSQL 11.3.0.629. Can you advise?

I updated to version 12 and I have now the same context menu, all good, sorry I didn't try that before I posted the question :-|
