Just want to say we've noticed it and it's on our bug list. We have to see what's the reason first - looks like edge case, but still it shouldn't happen. Sorry for the inconvinience!

I guess that's because we have a very similar bug connected with changing your username, also hard to bite.

I'm sorry we had you wait and think that we don't care about it.

No... I meant username generally.

I didn't state that you have changed your username - I explained why support asked you if you did it.

About other things - I'm sorry, I don't know. Please search for information in http://www.gog.com/support - especially in "GOG Galaxy - troubleshooting and useful information" and your game support subpage. Send a ticket to support about this specific game (if you didn't already). You can also create a forum thread (or check on this specific game forum) and see if other users did encounter similar problem.

Our developers made a fix. Please check if your issues with chat and tooltip issues are resolved.
I see your tooltip is opening now and I have started a conversation with you.
