I have a need for a Greek alpha-bet with some classical Greek characters added. I had no trouble using the program but a couple of characters needed improvement. I have done this but when I save the upgraded file, the changes are not written. The original file is saved.
Gene, I've had no such troubles. What comes to mind is: Maybe the changed file was stored in a surprising location (like the directory you specified for a previous Save operation), and maybe you didn't really save it. As a test, try again, make a simple change to the font, open a Windows Explorer window to the directory containing the font file, save the file, and verify by timestamp that the file was saved. If not, use the Search feature to see if it wound up somewhere else.
If you were editing an INSTALLED file on Windows, especially one that was in active use at the time (for instance, selected as one of the fonts for Windows, using Display/Properties), there are several reasons why it would not immediately get reinstalled. If the file operation succeeded, the font might take effect the next time you restart the computer. I've described nearby a non-standard laptop on which even Fony's Install operation took an installed font completely out of service for one entire restart cycle.
