The game was randomly crashing in a 9 hole solo game I had earlier, no particular hole. It crashed with the above posted error message around 6 times during that game. I'm going to fire up a round now, and submit if it happens again (after a reboot and flushing of internet and flash cache).
edit:
game ran fine in solo, so i guess one of the 3 things i did fixed it, though i suspect it was the flash cache needing flushing.
