TWO STUPID BUGS:

If there is a lag in the game or your internet speed drops; you get connection error and the "reconnecting" doesn't work - what's the point? The lag that crashes the game then leads to another bug - not being able to use hotkeys - if you get disconnected you are taken back to the log-in screen; if you re-log in after this and play a game you can't use the hotkeys.

I experience some problems after a reconnection attempt as well.
My problem is that i cant type in the lobby or in game after logging back in. If i close down the java and restart from this rather than just logging directly back in i find i dont have any problem. Maybe you could try this in the short term until a more permanent solution is found for you.
