For the test, I updated Miranda and plugins to the latest versions, of course GMail notifications do not work with the latest version
I am posting some of the netlog information, I don't know if it's helpful - but the whole netlog has my private data so I can't publish it.
In this part I am attaching I also changed some entries to xxx
Is this information sufficient?
