Well, should not and did are two different things. All I know is that I changed the font setting in FireFox and now I can read the check off list. And there have been no problems reading other sites nor programs.
You are right on the 800x600 and I have 16 bit/hi color resolution.
And this is an ancient 'puter, built in '97. But, being a farmer, it is all I can afford. Although prices are starting to drop. Maybe by Christmas, I can get a new one...especially if it will rain here in East Texas.
BTW, I "solved" the run time error by uninstalling CC and reinstalling it. After the reinstall, fonts were the same; thats when I changed the setting in FireFox.
Again, thanks to all for their time and suggestions.
