As Outlook 2010 is supported since PGP 10.2 some response would be really really nice. Otherwise you should just sell your software without support!
Can't be that difficult to let your customers know when next version will be released (just in case your software developers knew what they were doing.)
Sorry for that, but it's kind of frustrating to ask again and again for month and nothing happens! So thank you very much for the 2 month old info that this is a PGP bug!
...and now do your work and fix it!
