Problem with scripts in ksh

   Is this some obscure feature I don't know about? :-)

This sounds familiar.  No promises, but is it possible you're doing a
`set -o monitor' in your .kshrc/.profile?  As I recall, setting `monitor'
in a non-interactive shell caused ksh to hang after executing an external
command in a script.  I'm afraid I don't remember which version of ksh we
found this problem in.

Hope this helps.
