In his post Ron asks about having PGP automatically prompt for a password when the device resumes (see https://www-secure.symantec.com/connect/forums/after-computer-sleeps-i-need-re-enter-passphrase). The problem is listed as solved, but in reality it's not.
I have the same problem. I need PGP to prompt for a passphrase after resuming from hibernation. I am not using whole-disk encryption. I use several separately mounted encrypted disks, as well as ocassionally encrypted or signed email.
I have found that if I don't enter my passphrase the email proxy in PGP does strange thing when running in disconnected mode and then later reconnected to the server. If I make a point to enter the passphrase no issues arise. Unfortunately, since I am not using WDE, I don't get prompted on resume.
I will reask the question that Ron asked in his post: Is it possible to get PGP to prompt for a passphrase on resume, similar to the way it prompts for a passphrase on boot. I've looked everywhere and I can't find an option to do this.
