Alt+F4 ends up in close&start

Hi!
To the point: on my Logitech mouse I have assigned a button to emulate Alt+F4 command to close a window or an app, classic command. Everywhere else it works great, for years. But emClient - it ends up in closing emClient and then starting it up again, and over and over until ! really manually (like an animal :stuck_out_tongue: ) click on the x in the corner.

And it’s totally random! To my knowledge and experience, there are no reasons for it to happen

So, whats up with that? I can’t even think of a reason for it to happen.

Mid-this-message I restarted my PC and then changed the logging preferences to “all” (develepers: hint!) e.g. changed the log settings to log everything, applied and it happened again! Then “put it down” and it “stayed down”.

FFS, it’s like Walking Dead, only scarier!
