Hi, panworks:
As a possible interim workaround: the bug seems to be related to the amount of formatting done in Page Layout. Setting that to the Default ("d" key from the Page Layout view) can sometimes fix it.
Also, I've found that a file that gets truncated on PDF Export will sometimes export properly after a re-boot. Not always, but sometimes.
Another possible workaround is to convert part of the file at a time and trim and join the parts. To do that, simply move the displayed page (in Page View) to the page after the one where PDF export stops and export again. It might take several exports to get the whole file converted. Eventually, you will get all the pages, but with extra pages at the end of the later ones. You can then use a program like PDFTools (
www.pdftools.com) to trim and join them. And it's free!
And, as Reinhold says, a fix is coming.
Good luck.
