Navigation Pane does not navigate.
Clicking on the icons on the left hand side of the work area has no effect whatsoever. I cannot view or insert bookmarks by clicking on the bookmark icon. I cannot get thumbnails by clicking on the "pages" icon. I cannot view comments by clicking the "comments" icon, etc.
Trying View > Navigation Panels does not do it either.
This is a major functionality impairment for me.
Help.
Try reparing your Acrobat installation (Help > Repair Acrobat Installation). If that doesn't do it, do a deinstall/reinstall. Make sure all versions of Acrobat viewers are deinstalled before making a fresh new install.ted
