I am having problems with a custom footer in my document. On pages "v" and "x" in the front matter, the text shifts up slightly. The best I can figure is that the whitespace above those two page numbers is being absorbed for some reason. How do I force the page numbers to occupy the full height of a character, so that the footer does not shift from page to page?
Currently my footer is defined in a custom page style as:
\hrule width\textwidth height 1pt%
\hrule width\textwidth height 1.5bp}
\scriptsize Version X\hfill\small\thepage
I previously tried creating this footer with fancyhdr, but was unable to figure out how to get everything in the right place on the page. This approach works, other than the slight vertical shift on the two pages in question. (This is a reproduction of someone else's MS Word template.)
