I have loaded a powerpoint slide on a page viewer web part following instructions I have used before. In powerpoint, all of the hyperlinks work, but as soon as I add it to my sharepoint site, the buttons are no longer clickable and it doesn't take me to the document library I have hyperlinked. I've tried saving the file as a web page and as a single file web page, but neither work. The image appears fine, just the links which are no longer working.
I have done this before, but I have been upgraded to Windows 7 since - could this be cause ?
