Evening Sky Panoramic w/ AutoStitcher

Two shots taken (11july 09) with my iPhone were stitched together with AutoStitch app.
 
Chicago Evening Lakefront using iPhone apps: iFlash & AutoStitch.
 
Hey iFlash, what's up with that lousy bug that creates a line on the right side of the image? It doesn't happen in any other iPhone app and can not be duplicated when just using the regular iPhone camera app. (the line is not in the original photo..)
 
just trying some things out..
Thanks,
SG
