open process on OSX?

[Yennie at aol.com]

List,

Can't seem to get open process working on OSX.
If I do the following:

open process "/usr/sbin/sendmail"
answer (the result)

I get a long (say 30+ seconds) delay, followed by an error.
In those 30+ seconds I can see sendmail jump to life (in the process viewer 
app). When it finally gives up waiting and quits, I get my answer dialog.

Works fine with the equivalent Darwin engine / CGI script.

Further, if I do this:

open process "/usr/sbin/sendmail -t"
answer (the result)

I immediately get an error- any command line options seem to trigger an 
instant error with all processes I have tried.

Am I doing something wrong?
