What makes everything on a card unresponsive?

[Graham Samuel]

Hard to extract, but I have a new idea - what if the message queue is being swamped? I have flimsy evidence that the simulator is generating locationChanged message (odd, because I don’t think it really has changed). Can I interrogate the queue?

Just feeling my way.

That card contains buttons and graphics which lead on (via very simple MouseUp handlers) to specialised menu actions, each on its own card. One can return to the main screen from each of these action cards.

But when I get there, sometimes some of the menu buttons work, but sometimes the whole card becomes unresponsive, so that none of the buttons work, not even a ‘cancel’ button whose job is just to go back to the main screen. This didn’t used to happen, so I have messed up somehow. But my question is, what sort of action would make an entire card unresponsive? Maybe the app is stuck doing something I can’t see, but what could it be?
