Automatic Page Filling

[Sawyer5E81]

My PDF's keep changing zoom when I use a bookmark.  I've used Edit > Preferences > Page Display > Default Layout and Zoom function to get it to open at the right Zoom, but I can't figure out how to keep from changing on its own.  Is there a way to fix this?

It is only possible when you change the bookmarks. This is not possible with Acrobat Reader.

The zoom setting is a part of the action associated with the bookmarks, as the author of the file set it to be (knowingly or not). You can not disable or change it using the free Reader.
