I have just opened the Mysterious Box to get the last item on its display. In fact I've done so 4 times this evening.

Each time, the multicolored box that appears has been added to the pile on top of the mausoleum's corner--and immediately the game has mostly frozen. I say mostly because villagers come and go, but I can't select them, I can't select the mausoleum, and I can't move the display to any other part of the island. Or if the lemur finds something, that info appears but cannot be clicked away.

Each time, I have closed the game after the freeze--most recently while letting it sit for several minutes in (vain) hopes it would get around to saving the action. Each time, I've come back and the Mysterious Box soon becomes available again, shining in the shallows, while the bright-colored little box from the previous iteration is displayed on the mausoleum.

In case it matters to know, I've opened the box w/ a different villager each time.

I now have 6 multicolored boxes piled up on the mausoleum. (One appeared spontaneously a few days ago for no reason I could assign, with notable tremors, and was added on top of one I hadn't noticed before.) I've decided to leave the blasted Box where it is until I get a helpful answer here rather than adding a freezing prize.

Note that I bought the game thru Big Fish, which apparently means that the gear button does not make a Help button available. If I need to contact their Help desk in order for someone to look at a file w/ my data, I know how to do that. However, I'm asking here first!
