Scott,
I will try today to encrypt and decrypt both on the win98, however
I need also (winXP-->win98) and vice versa.
Could we communicate together via email?
It will be faster, I think.
Please write me at: ania_de2004[at]yahoo.com
I will let you know the results asap.

ps: I tryed to reach you under scott[at]msdn.com.au, but it doesn't work

regards,
Anna
