Hi BrowserUk,
Thanks for your reply,- So how come this works fine when run from DOS command or e.g. via the Task Scheduler?

I have a different script for scheduled report execution which calls it self a number of times in detached processes and in turn executes other Perl scripts depending on which parameters is passed to it.
This works great!

So thís problem only appears when run via the web interface.
I can work around this by executing the detached script via a system command from the CGI script, but this isn't nearly as elegant.

Cheers, Kristian
