Need help problem decrypting email

Im using version 2.0 of gnupg4win with win vista and Outlook 2007.
Signing works perfect encryption seems to work as well but getting an encrypted email I can only see a blanl email with two attachments one .bin and one .dat
Manual shows a popup to decrypt emails but this popup does not appear on my system- any idea?

Just found that it works fine in Send Items but not in inbox
I send myself an encrypted email - I can decript it in my send items but not in Inbox and not if I move the mail to another folder.
