I've been playing with this BIAB 2009 software for a couple of weeks now. I basically like it but certain things are driving me nuts. During chord entry, I'll sometimes hit a wrong key or click in the wrong spot by accident. To correct my error, I'll try the "undo" under the Edit menu but then I'll end up with something really crazy. Right now I've got a gray bar in the middle of my song. There are no bar numbers in this gray bar, so I don't know what it is. I can't seem to get rid of it. Very frustrating.
