I have the same problem.
I tried changing from 120 to 96 DPI to get back to the original setup, but the result is an even smaller font.
So I tried to delete all the PANOGREX settings from OS2.INI apart for the shadowbuffer setting, but after a reboot nothing was changed, as if it remembered somehow the settings.
Then I tried setting all the parameters as per your message, then rebooted. Once again nothing changed (still tiny fonts).
What do I have to do? Yes, I could disable PANOGREX, but there HAS to be a way to keep it and have the font settings as before.
Could you please detail which PANOGREX settings correspond to each of the SDD settings? And what are the defaults?
For example: if I want to have the same effect as
which are the parameters and values I should put into PANOGREX?
