This weekend I had 4 clients where the scores did not update anymore and closing those clients or sharing a solution from those caused a hang. BTW, the connection button was still on, telling the connection was there.
Why not implement the following:
- if a client (on an active puzzle) has not received score updates during a certain timeframe, close and try to reopen the connection.
Give a message in the window where announcements are made if the connection making failes to get a response. (But keep trying every 5 minutes)
- when sharing a solution does not give a response within 30 seconds, give a message trying to reconnect.
30 seconds later if still not connected, give up to try to connect and return control to the player.
- same when closing a puzzle or changing tracks except that the requested action is still taken, maybe with an extra question when closing.

Hope these suggestions will be implemented.
