NOTICE:
You are running Mozilla, which has a nifty little feature called Type-Ahead-Find. Unfortunately, this interferes with the game. In order to play the game properly, you must disable Type-Ahead-Find. To do this:

1) Open a new tab or window and type "about:config" in the address bar.

2) In the Preference Name column, locate accessibility.typeaheadfind

3) In that row, double click the "true" in the Value column

4) Type "false" into the dialog box that pops up and hit ENTER.

Believe me, this is as annoying for me as it is for you. Sorry about the inconvenience, and I understand if you don't play the game as a result. You will not be shown this message again. Remember, it's about:config!!
