Question regards session key error

[Matthew561@aol.com]

Hello,

Looking for help.  

Running PGP 6.02 PGP, 2.6.3ia-multi05 and GNUPG 1.06.  Messages generated 
with any version of PGP, no problem; however encrypted messages created with 
GNUPG crash with a "bad session key" error if opened in PGP.  I have RTFM, or 
FAQ, but I can see nothing about such an error or how to address/fix.

Does this have any relationship to the fact that I am sending test messages 
to other useids that are also on my secret keyring (from me to me as it were)?

Any ideas as how to fix or explain

Please respond or CC off list.

Thanks.

Matthew
