I am using BIAB right now, and just hit this twice, and it is minor pain in the butt. My mind is on the music, and I just want to change the tempo by 10, and suddenly I have to switch gears, think about BIAB, and get things adjusted right.

I can also tell you that I spent a month thinking there was something wrong with the buttons on my laptop, because "once in a while the left button seemed to activate the right switch." I thought there was something mechanical wrong in the switches, and so I was always trying to push the very left part of the button, in all applications. I was even thinking of opening it up and cleaning the switches. I finally realized that it was BIAB.
