Man... I have never had so many issues before. Crashes. Lots of them. Deleting some 3rd party vst synths locks it up and crashes it. The help module keeps showing up. I liked the synth rack where it was.

All the other previous updates have been great. This one... not so much.
 
Anyone else suffering?

I've been experiencing a lot of random crashing when trying to open some projects, other than that not really any other issues.  I do wish they could have kept the Synth rack where it was though.

September was my last update due to the issues everyone else was having. Honestly, I think I'm done updating. It was a good run but I've grown weary. Currently my only issue is crashing when I side-chain but that's no big deal. Love Platinum to death!

I'm back to 10 on my desktop, I had to roll back to my last image file.12 was that bad, rolling Sonar back didn't really "fix" things. 11 is running fine on my studio rig. Couple little niggles, but I would call it stable.
Once bitten twice shy, I'll be very cautious installing 12 in the studio.

I stopped at September too.  I'm kind of jittery about going any further because of all these crash reports.  And like Jeff I LOVE SPLAT.

I've been ok, really. I'm in pre release for December.

There seems to be a lot of mixed reviews. I happen to be having great success myself.
My PC/System is less than a year old (Intel I7 4700k 1150LGA) and my Audio card (Focusrite 18I8) has the latest drivers and im using Windows 8.1.
My projects consist of both Audio and Midi and I use potentially 30 - 60 plug ins per project. Ranging from some of Cakewalks stock plug ins to Waves, Softube, Overloud, exc)

I'm on December early release with Windows 7 64bit fully patched using ASIO drivers.  I must say I have not had any of the crashing issues... I use all of the synths mentioned in the pinned post.

Win 7 64 here. Weird behavior and a couple of freezes (one when saving). Going back to the September release for now.

All good here. You can put the synth rack back in the browser: Views -> synth rack.
