We get hordes of spurious warnings regarding Jack and Hijack when starting up Slow.

Is this only true on my system? Assigned to Warren to check it out...

You know what the Jack Server is, don't you? Multichannel audio bus. This is what I get on startup:

[rec]

Oh, thanks, this is very interesting! You get a shorter set of messages that fail to find Jack! (The GDB stuff won't happen when we run without debug...)

This is good - it's part of my "understand each line of our logs" policy. If we can keep our logs useful, we can log truly "exceptional conditions" and keep the code really solid ("we know that we have never encountered this condition or we'd have logged it").

I can't count the number of times I debugged something and then later noticed something that would have saved me a lot of time in an error log somewhere.

I feel that JUCE is fiddling with Jack somehow, I'd like to try this on a clean machine sometime.

I'm going to close this then.
