Thanks for the word doc. What I was referring to was zooming that occurred from pinch zooming. If you never pinch zoomed, and are still seeing problems with how the song is rendered, you can always try applying a very minor amount of zooming to see if it fixes the disappearing lines (assuming the problem is related to scaling).

Are these files PDF files or image files? You mentioned Adobe Photoshop, so I'm assuming image files. I believe image files are more prone to this kind of error than PDFs in MS Pro. If you can send me one of the example files that is causing problems for you, I can start investigating if there is anything I can do to provide a higher quality rendering.

Thanks,
Mike
