John,

If you re-read the beginning of my post, you'll note that this problem has been observed on at least 3 different hardware platforms. I observed it on two different Windows PC's, one running Windows 7 and the other running XP (SP3). I have observed the problem with two different Builds of BIAB 2011, Builds 312 and 319b. Also, PG Support has confirmed the problem as well, and they probably tested BIAB 2012, since they always check out the latest version for issues. A "bad video driver" is not likely!

This past April, I discovered another display problem and reported in to PG Support:

PG addressed this problem with the release of Build 318:

Summary of Changes for Build 318 (May 30, 2011)
Improved: Sometimes after resizing the main window, parts of screen wouldn't redraw.
Added: Some new style definitions.
Fixed: Sometimes using metal guitar soloist, would play a "too long" riff.
Fixed: Save Soundtrack wasn't working if the song was playing.
Fixed: Non-English versions only: Medley names were messed up.

All we're trying to do here is help to identify the root causes of the problem and make users aware of a potential problem, and perhaps make it easier to develop a fix.

Shoot me an email and I'll send you some of the song files that seem to provoke the problem.
