Performance coming up - Which jj version is most stable

Hi, I have the latest download going from JJ. I have a show coming up and I'm starting to worry a bit after reading all the bugs people seem to be having with the current update (especially the gradual pitch changes). Which OS version would all of you say is the most stable right now? I don't care if it goes back a few versions.

Thanks,

Saul

i already played about 40 gigs this year, never had any problems with the newest update. why should the os hang while playing back a seq...?
