After making lots of edits to my book today, I noticed there’d been a page creep. I eventually tracked it down to the number of lines per page dropping by 1, because it seems that LO is now reserving an extra blank line at the bottom of the page.
A screenshot that shows a page from an earlier version of the book on the left (before I accidentally changed some setting), and a page from the current version of my book on the right, with the extra blank line area highlighted, is on my web page at image:
I suppose my question is, “What controls the spacing in this bottom area, near the grey registration marks?”
I must have modified the page style, early in the day, accidentally. I clicked the Reset button on the page style, and didn’t noticed any change (until 10 hours later!).
I compared every aspect of the Page style I could in that page style, between the earlier book and the new one, but all settings seemed identical. I even tried setting Register-true (didn’t help), and activating Asian languages so I could use the Text Grid and change the number of lines: but that seems to be altering the font and leading, while still leaving the new blank line reserved at the bottom of the page.
There’s also the occasional rare page that doesn’t have the extra blank line at the bottom: the first one occurs on p185. It is the same page style (“Convert8”), and examining every tab of the page format, I can see no difference for this page. But it has the number of lines per page that I want. p185, p188-190, and p513 are also correct.
Please help!
