XP was probably MS's best OS. I mean, out of the box, it was stable. I had Win7 lock up my hardware due to Flash of all things.

I did find a way to mute the tracks in BB10, thanks, but I went ahead and got BB2015 anyway.

What I want to do is use BB to generate tracks, then replace those tracks with me playing. I have not figured this out yet. (I'd say I'm disappointed but I know it's my ignorance, not the program's capability, which is pretty impressive.)
