Publish as PDF problems VISIO 2007

[Nathan]

Recently I have been having problems publishing my drawings as a pdf.  I get an error message when I attempt to publish some fill patterns that have been rotated.  This happens with fill pattern 29 for example.  In addition I find that I get an error publishing for seemingly no reason and the fix seems to be slightly relocating some image on a page of a drawing.  Of course finding what part of drawing needs to be moved is a nightmare.  Anybody know what is going on?
