Just to get that issue out of the question: Yes I know 9.04 is not a supported platform… 
Nevertheless; It’s not possible to launch attachments (open/edit) from email documents.
This problem is verified on several installations.
Anyone who can think of a reason why this does not work?
Thanks

Subject: Same problem here - Can not open or Launch Attachments
I’m having the same issue.Ubuntu 9.04 - Notes 8.5.
Can not open or launch any attachments.
I’m finally making progress on getting people to serious look at a Non-Windows alternative but it’s the little issues like this that send them running back to MS.
Any help?
