I hadn't even noticed the 'bet per click'.  It gets reset to 1 for me too.  "per click" in the wording seems to suggest that each click will bet that amount, so if I click twice on a number it bets twice that amount (see my second comment in my previous post).

Also I'd like to see the 'x2 +1 -1 1/2' buttons next to the 'bet per click' box, just like there are for the bet sizing box for blackjack.
