Hi,regarding the thin hairline - I discovered it is the "Show page numbers" which causes the problem. I set it to NO because I don't need page numbering now. So the problem is solved - although I think you should look into the matter in case someone else encounters a similar issue.
I do have another issue - When you open the menu where these modules are, it takes a second or three for the articles to appear in the flip box. It opens first with the whole article spread out over the page before it drops into the flip book. Can that be solved?

Apart from that - It is a really great module! I love it. Thanks.
