Just start the reader executable with no arguments. os.system(r"C:\Program Files\Adobe\Acrobat 7.0\Reader\AcroRd32.exe") Does it for me. If you need to send commands etcto it you propbably need to to use popen()/commands/subprocess depending on your preferences and Python version. > to run two Adobe Reader sessions simulatneously. Yes of course but to communicate with them you will need to store the pipes in different variables. An alternative approach is to use the WSH COM objects, but thats a whole new topic! -- Alan G Author of the Learn to Program web tutor http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
