So i have had OS 4.5 beta installed for over 24 hours now. During this period of time, I have had it on for about 20 hours.
Twice now i've heard the blast of "satan saw" on my Polar, which i havent had since the early versions of the OS.
This is under mild use with and without Cakewalk Sonar X1b. The last time it was just sitting there and it triggered it.
