How do I undo this?
I have been trying to open a file that a friend sent me as an attachment. when it said which program would you like to use to open this file i started to work my way down the list. After several unsuccessful attempts ( when i HADremembered to un-check the box) I forgot to un-check the box that says 'always use this program to open this type of file'. Does anybody know how I can get back to or undo this mistake. everytime i try to open the file it tries to do it with Acrobat reader 5.0 which is un-suitable. BTW I think that the fact that the box always checks as a default is bloody annoying. The file I'm trying to open ends with jpg+.sit
