All I can say is I started a game last night and on my first putt the mouse click didn't register until about 1 1/2 secs after I clicked. Thought it was just a fluke until I tried to make the 3 footer coming back. Checked my system prefs > Flash and sure enough there was an update yesterday. Installed and everything went back to normal.
I use Macs so it may not affect Windows based computers.
