Sonar Platinum - Omnisphere 2 Issue... Browser & Knobs not working... Sluggish at best

Hey All,
I've had Sonar since Sonar 8 and Omnisphere also, everything has worked great for years. Until now.
Open a blank project, load Omnisphere 2 (multi out) and the browser to pick your patches is almost inoperative...
extremely sluggish. After messing with it awhile you can eventually get your patches picked but if you try to tweak the
patch it's super sluggish too making it near impossible to edit sounds.
The previous projects also have the same symptoms now also.
 
Same computer for years, no new hardware, Win7, 16gb ram core I7.
 
Any Ideas or others having this Prob?
 
Thanks!
Ram
