Re: XPI question

Hi David - Perfectly OK to write to me, except that I don't know the 
answer to your question. I know that this level of interaction with the 
OS (i.e., ShellExecute) sometimes has problems that require special 
solutions--I am thinking of Python and difficulties that people have 
with os.system calls--but I don't know what those solutions are, so I am 
posting your message to the netscape.public.mozilla.xpinstall newsgroup, 
where the pros hang out.
