For me, it might be the identical topic as the scroll wheel disable. I'm not sure there has been any issue that wasn't related to the scroll wheel for me, except thinking I was modifying one track when I was modifying another (this was user error). So... :-) I'm really pretty happy.
One small thing... Sometimes the little bouncing line on the Sonitus compressor doesn't bounce on the line and it makes me wonder if it's working. I get very confused when the user interface stops performing as I expect. I abandoned attempts to use side chain compressors twice in my current project ( but again... probably user error ). I could get the thing to bounce when in the FX bin and not using side chain, but when in the Pro Channel in the FX Chain it didn't work as I expected it to.
