2) I want to register: How to do that?

Under OSX

you have to pay a small fee. Take note of the"internal code": it shuold be typed in when registering.

Go to this page:

BCI_Register.html

You will receive an Unlock code: put it into the second field as shown below:

Under Classic/OS9

registration is FREE.

p.s. You can anyway USE the program: the only limitation is that it will ask again to register next time you open it.
