file-roller and bzip files

[James Lawrence]

I think what you do is right click the file and you get a menu  to open 
with...  there is a option to open with a  "other application"?  sound 
familiar?  there it opens another menu, and shows the applications that 
it will open it with as default.  down at the bottom is "Go There".  
click that,
and  in the program to run box type  in the name of the program you want 
to associate with your bzip2 files. OR, when you right click the file 
and click "other application" in that menu, click "modify" and and 
select don't include in the menu for "  " items. see if this helps you. 
if i'm off base, let me know.
