Please use fixed row width (percent or so)

I really love what you guys have done and 4.3.4 is awesome. But could you please please fix the row width jumping? It even varies when going from File 9 to 10 due to the text being 2 digits wide.

Many many thanks

Why am I having to download a thing I know nothing about just to view the file???
Call me Mr Paranoid if you wish, but no thanks.

Because I added several images to a PDF so that I dont have to upload all of them separately. Since there is no native upload for pdfs here.
Edit: And what free file service would you recommend that people would instantly trust?
Edit2: Removed ugly remarks
