Old question - didn't find an answer. CS5 on Windows 7. Can't change the fonts or line weight. Fonts do change if using type/font pull down, but not from character box. Just installed on home computer as I wanted the same version I use at work.
Set the fonts back to 100% in the operating system or turn off aero theme.
If that's not the problem, see Replace Your Preferences
Thanks so much - will try.
I have your advice as a backup to Bob's. Much appreciated!
