Bookmark vertical location seems slightly off for some paragraphs

[MaxInCO]

I have a template with a list of items in the form of paragraphs using 8pt Arial and vertically spaced at 6pt, much like a bulleted list, but NOT a bulleted list. At the beginning of each paragraph is a bookmark, for which I calculate the horizontal position, vertical position and the pagenumber, which are stored in arrays.

Then, via some VBA code, the template is populated with a series of docvariables and output as a PDF. Next, some embedded javascript takes over that opens the PDF and, using the arrays mentioned earlier, adds checkboxes to each bookmark location.



I understand that Word does forms and checkboxes and all that, but there is good reason why I'm doing things this way.

The problem is, on the second page three (3) of the checkboxes are slightly off in the vertical direction, probably no more than 2 or 3 points. This isn't the end of the world but it makes the form look slightly unprofessional and I'd just like to fix it.

I believe I have checked all the formatting settings in the Word template with respect to line spacing, etc., and everything seems OK. All of the bookmark locations are calculated using the same code so I can't see that as being the issue.

Does anyone have any ideas why certain bookmarks would be different vertically than others?

Thanks.
