This is beating (heterodyning) with Coco's 60-Hz vertical frame rate, and causing the slight drift in vertical position. Only fix is to replace the big electrolytic cap, or better yet add another one in parallel with it. I doubt very much this is the WordPack's fault. (I have one I'd love to sell cheap). Sounds like there are lots of Coconuts at CMU, my PhD alma mater. Do you know Walt Wimer? --mike k -- "Round and round the while() loop goes; Whether it stops," Turing says, "no one knows."
