nWhen the 'Uh-oh, an error occurred' dialog pops up, and you type in your explanation about what you were doing, the keystrokes cause things to happen in the game. So, for example, if I type:
"I was just looking at my garden"
the Quest Log pops up in the background when I start to type "looking". Another 'l' causes it to disappear again.
