I'm using eclipse 3.0.1 with pydev 0.8.5 on win2000 when renaming variables, methods, class or extracting methods, plugin takes a while and then simply do change nothing.nothing happen...Did I miss some config?
It seems that you are not being able to connect to the python shell process for the refactoring. You can try to raise the number of attempts to connect to it .
(go to window->preferences->pydev->code completion and raise the number of attempts - it takes longer on some machines than on others)
If that does not solve it, please paste what you have on your error log (go to window->show view->error log)
