How do I change the application that automatically opens pdf files attached to emails?

more options

When I first double clicked a pdf attachement in an email, a pop asked what program to use and if i always wanted to use this program. i select an app to open these files types and then checked the 'yes' box. However, I selected the wrong app. Now, that app tries to open all pdf files. I need to change this to the correct app. How do I do that? thanks.

Tools (Alt-T) - Options - Attachments - Incoming Look for PDF in the 'Content Type' column. Then adjust the desired action in the corresponding 'Action' column.

Could you try:

"3-bar" menu button (or Tools menu) > Options > Attachments panel > Incoming tab

Can you find a saved setting here for PDF that you can edit or remove?

(Mine's blank; I guess I haven't saved any settings yet.)
