When things are not responding quickly (and when some clicks seem to get lost), apparently, I have a tendency to issue an extra click.
This caused me headaches yesterday with the giants, because an item was donated without my intention. Worse, I couldn't even tell what had been given.
So,
a. I think there should not be a default item selection for the giant donation thing
b. There should be a message about what you actually gave, more than "oh, one of these?" kinda thing.
Oh wait. It probably wasn't a default item selection... the second click probably selected a specific item that happened to be under the mouse. I wonder what the right solution is for that. But yeah, minimally, I'd like to know what I just gave up by mistake.
