Can I lock in a zoom level (e.g. Page View) so it won't change?

That sounds genius. Where is the "Accessibility tab"? 

Pat,

Yes, it does.  That setting tells Acrobat what zoom level to use by default when you first bring up the file.  I actually have the Fit Page setting in my preferences just like you show.  But once you hit the bookmark, the zoom level changes to whatever the PDF was created with for that bookmark.

I did find that I had a bunch of PDF files that have the bookmarks set to Fit Page, but in a file that has its bookmarks set to something else (like Fit Width), it will always change the zoom when you click the bookmark.

If you are interested, I just posted a crude way to modify this in your PDF files.

Thanks.

Thanks CtDave.  I don't have anything besides the free reader, so I did some further research on the web and found a solution that is pretty "brute force", but is an option for others that only have the free reader.  Here is a link to the full description:

Here is the basics:  You can use a text editor and edit the PDF file.  Once in the text editor you can search for /FitH or /Fit (there surely are other codes, but those are the only ones I know of).  These are codes that tell Acrobat what kind of zoom level to apply to the destination of a jump.  So the bookmarks should all have these.  Simply do a search and replace with /XYZ.  The /XYZ code tells Acrobat to leave the zoom level as it already is.

It might sound a bit weird, but I tried it on multiple files I was having trouble with and it worked great.  Of course, my suggestion would be to make backup copy of the file before doing this in case something goes wrong.

Thanks.
