Mario Teaches Typing: Type 1 Errors Caused by Preferences (7/94)
I keep getting Type 1 error when I try to open Mario Teaches Typing that came on my Macintosh Performa computer. Is there something wrong with the program.
Type 1 errors can be caused by many things. In the case of Mario Teaches Typing, it is a sign of bad preferences file. Throw away the Mario Preferences file that resides in your Preferences folder, then restart.
