Hi, I cannot recall the exact explanations, but when I set up external viewers for mutt I found that I had to use a program called `mutt_bgrun` that would detach the started viewers. It creates a temporary directory, copies the file into it and opens the viewer on that copy. It works flawlessly, only HTML attachments opened in Firefox do not reload. You may find mg_bgrun attached. Don't forget to make it executable after placing it somewhere.
In order to make use of it, I have a `mailcap` file residing in `.mutt`, which specifies how a number of file types should be opened. Instead of using the viewer directly, one has to prefix the command line with the path to `mutt_bgrun`. Due to lazyness I attach my complete `mailcap` file and not some excerpt. In order to make use of this `mailcap`, you need to add set mailcap_path = "~/.mutt/mailcap" to your `muttrc`. That should be it. Best, Max Görner

This causes problems when using graphical # viewers such as qvpview and acroread to view attachments. # # If qvpview, for example, is executed in the foreground, the mutt # user interface is hung until qvpview exits, so the user can't do # anything else with mutt until he or she finishes reading the # attachment and exits qvpview. This is especially annoying when # a message contains several MS Office attachments--one would like # to have them all open at once. # # If qvpview is executed in the background, it must be given # enough time to completely read the file before returning control # to mutt, since mutt will then obliterate the file. Qvpview is # so slow that this time can exceed 20 seconds, and the bound is # unknown. So this is again annoying. # # The solution provided here is to invoke the specified viewer # from this script after first copying mutt's temporary file to # another temporary file. This script can then quickly return # control to mutt while the viewer can take as much time as it # needs to read and render the attachment. # # EXAMPLE # To use qvpview to view MS Office attachments from mutt, add the # following lines to mutt's mailcap file. # # application/msword; mutt_bgrun qvpview %s # application/vnd.ms-excel; mutt_bgrun qvpview %s # application/vnd.ms-powerpoint; mutt_bgrun qvpview %s # # AUTHOR # Gary A.
