Hyperlink from Powerpoint to PDF formatting of pdf

Dear family

I have a PowerPoint 2010 slide show where I have created hyperlinks to .pdf files in Adobe 7 Standard. These are in the same file path as the PowerPoint presentation.

When I open the .pdf file from Adobe programme itself, it opens as set in its document properties (I requested in full page with hidden toolbars) and the page fits to the screen BUT when I open it using the hyperlink within powerpoint, the .pdf file opens but the view changes so it no longer fits in the screen as a entire page and sits offset so you can only see part of the pdf page.

If anyone knows why or how I can fix this I would be very happy to know 🙂
