Really? On my desktop where I did a complete clean install, I'm not having that problem.
Any idea what's causing it? I've gone through both /Library and ~/Library folders with a fine tooth comb bringing these folders back to a state that matches the machine with a clean install yet no luck. I've tried reinstalling Flash from scratch, cleaned out caches, etc.
A real bummer as Scrabs is really one of the best apps for Facebook!
