I recently used your instructions to obtain a personal certificate from Thawte. I believe I've installed it correctly - it appears in my keychain etc. and, when I attempt to create a new signed message the appropriate icons appear but are inactive for some reason. I've tried obtaining new certificates using Firebird and Safari 2.0.3; I've checked my keychain with First Aid, and I've specified that the Mail program has permission to use the keychain certificates. Nothing has worked. I'm probably just doing something stupid, but canpt figure out what.
Thanks for listening to my lament. I look forward to your reply.
