When I right click a .PDF file, the first choice is to use Acrobat Reader 9. The second choice is the "open with" menu and it has Acrobat Reader 9 (again), Open Office, and others.
The trouble is that the first choice does not work and there is no error displayed. The only way to open the file is with the "open with" menu. How do I fix this so that the first menu choice works (and perhaps so that the choice is not repeated in "open with").
I am on Ubuntu 10.10 maverick.
