Hi Bob,

The "screen redraw problem" does occur at certain times, and is fixed in this update.
Thanks for posting the detailed information on how to duplicate it. This made it much easier to fix.

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.

Have Fun!
