What should SeaMonkey do with this file?
O Open with [Browse...]
O FlashGot [...]
O Save File
 Do this automatically for files like this from now on.
Settings can be changed in SeaMondey's Preferences.
I want this to open in acroread (Adobe pdf reader), so I browse to the executable, select it, and check "Do this automatically...."
Next time I click on a pdf link, I get the same dialog box. I looked in Helper Applications of the browser Preferences and 'use acroread' is listed. There is an "Application Details..." choice in the drop-down menu and that shows the full path to this program, /usr/bin/acroread.
Does someone have some insight? Thanks.
