I have a lot of PDF- files in portrait format eg. bills.
When I doubleklick these files with MS-file-Explorer then Acrobat shows these in a standard Window. When I use Excel hyperlinks to show these files they maximize the window. This makes no sence with a widescreen monitor. So I have to dobleklick at the upper border to show it in the way I like. I didn't find any way to solve that problem. When I install F...t-Reader instead, It works fine.
So I don't think that this is an Excel based problem.
I think it's very easy for you to improve that.
Thank you very much for helping me.
