Following some 'advice' from a paid techie, I ran unassoc.zip and selected PDF to remove the file type association for .PDF I then ran the Repair option for the Adobe Reader. This was supposed to fix my problem. However, now when I click on a PDF attachment in an email (new or existing) that whole email message freezes on the screen! Needless to say, I can neither open the attachment or save it. The situation has now gone from annoying to desperate, so help to get out of this 'hole' woul;d certainly be appreciated!
