Sounds reasonable, but there must be something in the way that the
command is executed by e2, as well. I just tried it with the gimp, and
find that if I set command-xterm to "e2_exec gimp" and add a context
menu entry:
Test||false|false|$[command-xterm]|%f&
Then gimp will not be seen as a child, and I can quit e2 normally
without the confirmation dialog. Of course, everything has its problems.
If I try it with command-xterm set to "e2_exec mplayer" and play a video
file that way, e2 quits without complaining, but mplayer dies too!
I find that I can also add a normal "context menu" item:
Test||false|false|e2_exec gimp|%f&
And gimp will run "detached," as will mplayer (with the same problem
though... dies when I quit e2).
It's only when I try to add such a command to a "filetype" that I just
can't get it to work.
Oh well... one for the wishlist if I may. I wish that e2 had something
like the bash "exec" feature that allowed background programs to run in
a subshell, detached from the "terminal."

I see that in 0.1.7, after I have double clicked a file with no
extension. It doesn't happen if I right click and "view" but
for each time e2 does "autodetection" on a double clicked file,
it will "remember" a child process. They aren't in the list. A
command.list_children gets me an empty list. Rather than the usual
"no children" I see a "header" like:
| id | pid | command
|----|-------|-----------------
And e2 will complain of child processes running when I quit.
In any event, I only see that in the official release (0.1.7). I do not
see this behavior in the latest pre-release, (emelfm2-tom-20060621), so
I haven't thought it worth reporting.
ciao,
Jonathan
