Yes, I'm finding the same thing in 2010. I'm on XP Pro, a reasonably beefy desktop (2 gig memory), and not much other demand on the PC. It takes so long (haven't timed it, 12 minutes to do a 12 bar blues for 12 choruses), that I've assumed it crashed and then come back to it in 20 minutes and the song is rendered. I've CTL-Alt-Dlt'd and I see that BIAB is "non-responding", yet when I let it continue, it eventually finishes the job. Appreciate any ideas.
