WE RETURN, BACK TO OUR REGULARlY SCHEDULED PROGRAMMING::::

Happy to report on my iMac, that SR2 has made considerable improvements!

No Longer Crashing on the Library reloads,
No Longer Crashing in the Material Room,
IDL is MUCH quicker & does not "Lockup" 80% of the way through a render anymore
(well so far anyway ;))

I must have to look into replacing my mouse/tablet, the camera still does goofy things while try to directly manipulate within the preview window. 

Overall I am a happy camper with SR2
