Gary,
1. Do I understand you rightly, that my EXE file looks wrong on your another PC?
2. Can you install PTE on this PC and open this project in the O&A editor? Does Italianate font look correctly?
3. Please run the following 2 test EXE shows:
http://files.wnsoft.com/test/test-georgia.exe
Here I change your font to Georgia
http://files.wnsoft.com/test/test-italinate.exe
Here I used your original font Italianate.
How these EXE files will look on your another PC?
