> Thanks Mickael - I still have 7.7.5

I'm shocked. I didn't believe your signature :-).

I would be very interested to know/understand where those repeated login
events are coming from. As I said I applied a bunch of changes to 7.9
(only) to better understand and hopefully improve the situation. I'll
probably have to back-port them. But then you'd still have to update to
7.7.6... Any good reason why you stick with this ancient version?
