Hi, thanks so much for your help but I have not been able to fix it yet. I'll keep having a fiddle around for the time being :))
Well, darn! Does it still end up pretty much the same when you use the beta version, or is it changed at all?
I did notice in your screenshot that Safari doesn't seem to have a "Fit to Page" option, which I often have to use to get mine to work. Without Fit To Page, my little test A4 document will work at about 91%-94% Scale, although you already mentioned playing around with the scale & not having any luck with that either, so that may not be too helpful.
I wish I had Safari to test it out in! But I'll keep trying to come up with ways to make things fit better automatically, regardless of the browser--there may be some more tricks I just haven't learned about yet.
