It isn't corrected by quitting IDLE, but is put right with a restart. I am running 3.0.1 on Mac 10.5.6. Is this a bug, as it never happened on the same system with 2.5 &2.6.1 ?<br>Is there another way to prevent this?<br>Regards<br>John Forse<br><br>IDLE cant bind TCP/IP port 8833 which is necessary to communicate with it's python execution server. Either no networking is installed on this computer or another process(another IDLE?) is using the port. Run IDLE with the -n command line switch to start without a sub-process and refer to help/IDLE Help 'Running without a sub-process' for further details<br><br></div></blockquote></div>PS I AM connected to the network at the time and Help/Idle help is greyed-out on my IDLE. I've tried entering -n to IDLE on the initial blank window, but it seems to make no difference to the problem. I don't understand what is happening.</body></html>
