If it happens third time, I'll grab a screenshot and some video.

This has happened so far twice. At the start of the second phase  I'm unable to choose any card to play, other players have already chosen theirs.There are no costs or crosses at the top of the cards. Everything else works but I just can't choose a card. Clicking the card goes right through it - the effect is same as clicking the background. Tried leaving room and returning. Tried restarting the client. Tried restarting the client while all other apps are closed. Same result.  The only option left is to reset the game and after that the game functions as normal even on the same room and with the same players.

I'm betting on the following:
- There is server connection problem or slow connection
- The client loses sync and never tries to re-establish it (everything else works)
- This only happens with Mac OS X and it's default java

Still annoying...
