Auction House

If I have the winning bid and wish to move some points to another bid which is currently ongoing I want to reduce the bid. However in the Facebook Games Arcade when I attempt to enter an amount manually the complete bidding process disappears. This also happens if I try to increase a bid manually instead of using the buttons.
