Already running the 64bit client, and have been since it was released with no crashes.
But had quite a few crashes tonight in quick succession, every few minutes.
Deleted the 64bit client, downloaded it again and hey presto no crashes in the last 2 hours.
It might work for you if your having problems.
Jumping puzzles, love them or hate them, I hate them. Thread killer.
