Open Adobe Reader, go to Edit, then Preferences. In the menu which appears, click the link to "Internet" and then in the right hand pane, remove the checkmark from "Display PDF in browser". See screenshot.

I uncheck the boxes ( Adobe/edit/preferences/ Display PDF and Allow fast ), reboot the PC and still see the "Save screen" when I download an attachment.

any other idea?

THANKS

Where is the attachment? In an webmail email? If so, which webmail client are you using?

I work with mail.yahoo.com or ATT.net. I checked the mail configuration screen and I did not see anything related to download an attachment.

Thanks
