Programs to create a software walk-through?

[John Bartol]

I'll be archive-diving for related discussions, but a client wants to 
discuss this tomorrow, so any input would be greatly appreciated.

Client has an application with a character-based interface. Probably 
around 15 main screens, total of 40 screens including sub-screens.

Client would like to have a demo disk made that walks a user through the 
typical functions of the system as a training aid. Nothing overly 
fancy... not a lot of hours to allocate to this effort.

So... I'm downloading Camtasia right now -- are there others that would 
be worth considering?

Thanks.
