I use subprocess.Popen, because popen 1t/m 4 are deprecated. I found a dodgy way around my problem though. By inserting another page between the input and the results page,a user sees a "i'm searching" page which wants to redirect to the results page directly, but keeps waiting for the search process to finish. So I put what used to be my problem to good use. :D Maarten -- http://mail.python.org/mailman/listinfo/python-list
