I have just noticed that my mouse buttons are intermittently bouncing, but it's hard to imagine that could be causing random muting. Then again, It was only today that I noticed the muting.

I did a fast rebuild. I'll go ahead and do a slow one.

I have two other questions if you don't mind.

I found the "Obsidian" style in the picker which was perfect for my song. However, after the rebuild, that went MIA. Are there known reasons why a style would be showing as available but then proving to be no loadable?

Finally (yay!), I notice that the mute buttons in the mixer are sometimes red, and sometimes blue. Would you happen to know what these colors signify?

Thanks so much!
