I'm trying to convert a large MS Word 97 document into Acrobat using PDFMaker 4.05. I'm usually successful, but one particular document always hangs when Acrobat PDFMaker is "Converting Headings and Styles to Bookmarks". On the PDFMaker Bookmarks tab- prior to the conversion- I decrease the level of headings from 9 down to 3 in increments of one. When I only use three levels of bookmarks (i.e. Headings 1, 2, and 3), the document converts properly. On the fourth level (Heading 4)- when I try to convert- I get the hang-up during the aforementioned conversion process. I have to Ctrl+Alt+Delete and end the MS Word program. I've tried going to Format > Style to see if any of the headings contained any strange characteristics, but found none. I've gone through every heading in the document to make sure there were no formatting issues causing the hang-up. The bookmarks are essential to the converted document, as are at least six levels of Headings. I've spent several hours on this already, and any help would be greatly appreciated. Thanks.
