I (really) appreciate your independance towards Cakewalk, but if something is possible, some poor soul will stumble upon it and spend a weekend wondering what the heck is going on. So whether or not a situation is unlikely or dumb, a producer must strive to eliminate the possibility. And really, no action performed by a user can be considered dumb since you have to be experienced to know if it was dumb or not.
Well, I think that my using SONAR without having it hooked into an interface was pretty dumb...I just can't imagine someone wanting to work in SONAR and not expect to hear what's going on. So I assume someone's first concern if they're not hearing any audio would be "why am I not hearing audio?" Once that was solved, the issue of a groove clip that renders incorrectly when SONAR doesn't see an audio interface would no longer exist.
Which brings up the question of why I even encountered this issue...I use my laptop with an ASIO interface at the office, but often answer forum questions away from my studio or the office, so it's just the internal sound card. I'll boot up SONAR to answer a question and take a screen shot or whatever, but don't bother to reset the preferences.
That said, Noel did consider it a bug, but I would hope that it lives waaaaaaaaay down in the list of priorities. I don't think a common use of SONAR is to take screen shots from a program that can't function in order to answer forum questions.

However, who knows...maybe it's a data point that will come in handy when fixing some other bug that
does matter, which is why I reported it. But in general, I think "bugs" due to pilot error should take a back seat to bugs due to program errors.
