New Windows 10 (Ver 2004) and SMath 0.99 (build 7561)

I'll be updating old files and came across this gem of an error. Does anyone know what it is and how to fix it?

• All of my files are SMZ. I previously had issues with SMZ files and snippets.
  
• file will NOT open directly by double clicking the file
  
• file WILL open in SMath if I file open and point to the file within SMath
  
• portable version of SMath
  

I just opened a file that I've been using as a Template. The screenshots that I'm using in the Header and Footer have disappeared and the "Area" is not showing the bottom line 3Tier Calculation Sheet.smz (76kb) downloaded 9 time(s).... HMMM

Jean,
That's the problem. I had the app version and some header/footer graphics that went *POOF*. If you look at the "AREA", the second/bottom line that defines an area in the worksheet is non-existent
Windows 7 and 10 and using the last two stable versions of SMath gave me the same issue.
