When users try to open file attachments they only get the option to save only. This mainly happens with .PDF and openoffice documents.
I have installed the Adobe reader plugin and it works fine when using Firefox for browsing the internet and clicking a link in a web page.
I have also installed the Openoffice mozilla plugin and the only one that works is .xls
OS = Redhat EL 5.2 x86_64
