ibb4ub: should I start as a new member and forfeit all history.
Nope!
That would purge your playing history but not your PC's history. This is the faulty item IMHO.
Did you try a different browser?
How much RAM on your PC?
What is your OS and your browser?
Browser and Flash versions?
In general, cleaning might help (e.g., caches), and discipline in active tasks while playing.
