(OP) Yikes! I will check that out. Thank you for pointing that out. As of now, the four text buttons should say "Scramble", "Solve", "Record" and "Rewind".

(OP) Yikes! I will check that out. Thank you for pointing that out. As of now, the four text buttons should say "Scramble", "Solve", "Record" and "Rewind". I will check with Firefox to see if I get blank buttons with no visible text. The radio buttons have no labels or text associated with them currently. I will add little pictures next to them of the sub-puzzles they select.
