Hello,

I mentioned my problem a few weeks ago (I can not open my attachments
,such as postscript files,with an external application like gv) 

Even a clean .gnome tar which worked in another environment (thanks
John) didnt solve my problem

Does anybody know which file to edit and what the entry should look
like?

Thanks
Uwe
