Right, it seems that disabling plugins only decreases the probability of the bug occuring rather than disabling it entirely.
 
What about exporting audio? I have projects which don´t engage this bug at all until I export audio, then it appears.

Agreed - if this one bug got nailed Sonar would be fantastic for me. Each time a new update comes out I hope it is fixed, but no luck so far. It's hard to nail down. I've tried stripping down projects that exhibit the problem, but I can't find a simple project that will exhibit the issue repeatably. I wonder how else we can track this down?
 
Noel, if you read this, what can we do to help find this bug?
 
Cheers, Peter.
 

I typically experience this bug while mixing. I can't isolate any particular action, but usually changing plugin settings (Ozone or Sonitus reverb are the most common). But it can happen only on export. The way I usually know it has happened on export is when the wav file turns up silent. The wav file is not full of zeros though; it contains the largest negative integer as every value, in other words, DC. I can see this by importing the wav file into another program (Matlab). However, I use Ozone on the master bus most of the time. I don't know what values would be in the wav file otherwise.
