Menu in the way on Kindle Fire

I'm in the Fisherman's Hut, and I have the key to unlock the chest in order to get the matches. But the menu showing how many tasks I've completed partially blocks the lock, so I haven't been able to get the key to the correct spot. I've tried zooming in, but the zoom goes away as soon as I click the key.

So I know what I need to do and have the item I need to accomplish the task - but can't get any further because the menu's in the way. I've tried and tried to maneuver the key into the lock, but I just can't do it.

Which means I'm dead in the water - and VERY frustrated.

Any ideas on how I can get around this problem?
