I would call Sales and ask them what they recommend, or a refund.   This issue has been discussed to death in this and other user forums, there's really no way to properly fix bad font choices once the fixed size dialog boxes are compiled by the software vendor.

 - One work around is to set the screen resolution lower.  This will affect all software, not just Sage 50.  

 - There are some 'zoom' / 'magnifier' tools in Windows / for Windows but they're fairly awkward and time consuming to use.

I can read the screens, but would never use (what looks like) an 8 point narrow sans serif font for anything that I wanted other people to read.  For data entry I would go at least 11 point.

Thank you for your answer.  I finally found how to fix my problem while waiting in queue for online support.  Here is the solution that worked for me with a brief intro : 

History : Since I was a teacher in accounting techniques, I had an Education licence on my old laptop (ASUS ROG 2007) witch had a maximum resolution 1024 X 768 on Windows 7 Pro 64.  As you can imagine, I never had this problem since it was the recommended settings.  SInce then, I upgraded to Windows 10 and did not had the problem since the resolution was the same.

Starting a new job as Financial Director for a brand new company, I was provided with this new Dell laptop mentionned in my post.  Needless to say that it comes clean out of the box and had to setup a completly new Windows 10 pro 64.  Installed SAGE and BANG!  "Houston we have a problem!

The solution : 

While reading the hundreds of post on the same subject, two of them gave me a clue on what to check after trying, without success, the trick of running the program in compatibility mode and the DPI scaling ticked.

One of the post suggested that is was a Registry problem with the FontSubsitutes directory.  The other one mentionned it missing a font.  I looked at both Registry on my 2 computers and found out that in my new one (Dell) I was missing some fonts, Courier in particular.

I exported 2 directories from my old Registry (Ordinateur\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts  and Ordinateur\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontMapper) to the new one.  Restart the computer and BOOM!  IT WORKS!!!!!!!!!

I still had to tick the "Disable levated DPI...." option from the properties of the SAGE icon on the desktop but it runs flawless and, more important, I got my eyes back!

I can send you my .reg files for the fonts by email if you wish, just make sure to backup your registry before, just in case.
