Actually, I don't think that's it. It often happens when the window is active. It appears that the software just hangs when it is waiting for a response from the server. When it is in this state, nothing responds. You can't bring up another window, the check boxes won't change state, everything just gets stuck. I believe the problem is that everything you do is handled by the server, and that the software, even though it has multiple windows open, is single-threaded. The checkboxes should be handled by the client. If that were the case, the response would be instantaneous. When it's your turn to act, the client would send the action to the server, or if no box is checked, it would bring up the buttons. The checkboxes would be changed when another player's action renders your choice void, of course. Nonetheless, I will try making sure the window is active before I click a button or checkbox.
