Hrm.... I found this to be a recurring problem, likely caused when I did the cut and paste from the original blog version of my chapters....
Sadly, unless I can get the ability to re-edit the posts, I won't be able to fix them here, as this is the only
forum where I am unable to go back and edit the posts to fix the formatting problem.
However, you can keep from having to scroll so much by clicking the link at the top of each entry, that will take you to the blog version which has a locked aspect ratio.
Future entries should be free of problems, hopefully, now that I have an offline BBCode utility to do the conversions with instead of the forum post box
