alice-teacher Preferences not accessible in 2.4.1

Cynthia,
Try this:

In your home directory you will find a .alice2 directory, which contains your Alice preferences. Delete this directory, and then restart Alice… Alice will rebuild this directory, which hopefully will take care of your problem.

Keep us posted,

Later,
Don Slater
