Hi! For Windows, you can use the command-line tasklist
Example: tasklist tasklist /FI "IMAGENAME eq iexplore.exe" tasklist /FI "PID eq 4044" /FO LIST The last line is for known PID. Prior for search by (exe's) name. Note than STATUS give if the process is RUNNING / NOT RESPONDING / etc. And... tasklist /? for help. @+ -- Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
