I have a pdf with many embedded links, which I have placed in a typical SP2010 Page Viewer web part.
Any/all embedded links to a *.txt file, or another sites library directory listing, open in the Page Viewer window fine....and I can select 'Back' to navigate to go back to my pdf. works great.
My issue, is that when users select any link to a .doc/.ppt, the Page Viewer window turns GREY, and the doc/ppt opens fine in it's own Office window.
So the links work in all cases, it just with the docs/ppts, my Page Viewer window is stuck in GREY and I/users must re-navigate, to re-situate themselves on the sub-site/page viewer to access the pdf and thus any subsequent selection of embedded links...
Have I made myself crystal clear ?
