0.7.3 RC1 on OS X 10.7: keyboard issue

Greetings, all. STK is a terrific game that I enjoy immensely; thank you. Great work all around.
In 0.7.3 RC1 on OS X 10.7, I'm having an issue with the wired, extended Apple keyboard that's optional with current iMacs.
My key mappings translate fine from 0.7.2, but not all work. On the numeric keypad, 4 and 6 ("left" and "right") work fine. The 8 key does nothing (should be "accelerate"), 5 pauses the game (it's supposed to be "brake"), and 0 (should be "sharp turn") does nothing. The numeric keys above the alphabetic keys work as mapped (8 will accelerate, for example).
Also, I see an issue with the bowling ball. If only one bowling ball is on screen, it's the new purple style. But if more than one ball is on screen, the others look like the old 0.7.2-style blue ones. Example, if pick up multiple balls at once, all are blue. If throw a purple one and pick up a single one immediately thereafter, it's blue.
