Hi All I've received the message below and wonder if it's enough information for any one to help her. +++++ Just a shout for help from Ann R. she cannot get her PDF files to open. Running XP with JWF, using Adobe 6 and Direct X is up to date. Error message reads "internal Error" only Ok button available which takes several hits to react. Many thanks Roger If you can't be kind, at least have the decency to be vague.
