I've had it happen several times that my opponent has left, ostensibly resigned, I am credited with the win, but I can't close the window without getting the message: "the game is not finished, do you want to resign?" Even after waiting well over 5 mins, I can neither quit nor log out without clicking "yes"

Well, after no admin responded, I got bored and clicked 'yes' and still got the win, so apparently that's the way to go.

Yeah, the same thing happened to me, and I exited out of it the same way, so it just appears to be a bug with the server(or atleast the game window) thinking the game is still active even when it isn't.

Well, that's nice to know (clicking on the yes still gives u the win). The 2 times it happened to me i just killed the tygem task from the task manager !

Happy New Year to all!
Is there a new Tygem version out in the meantime?
I experienced the same bad thing: game won, but cannot exit without having to "resign". That's the last thing I would do after having had wet fingers and heart beating loudly

A while later, after "Ask a help" using without success ... resign.

Cheers,

Just quit the game, if it says you have to resign then do. It is just a bug and you'll still get the win as previously stated.
