OS X 10.4 and above ordinarly handles this automatically if you immediately try to restart the application. If it hasn't handled it, or if you are running an earlier version of OS X... I would first try: Preferential Treatment (free) http://www.jonn8.com/html/pt.html If that doesn't help, I would create a new user with admistrative rights, log in as that new user, and see if the problem continues. If it does, your problem is not user preferences related. If things are better, chances are that your problem is user preferences related. If the problem is likely not preferences related, I would try launching the offending program during a Safe Boot. http://docs.info.apple.com/article.html?artnum=107393 http://docs.info.apple.com/article.html?artnum=107392 If the problem is likely user preferences related, I would try manually uninstalling the ".plist" files for the offending application, found in: ~/Library/Preferences/ (Note that this is in your Users folder, in the folder with your user name.) ___________________________________________ Randy B.
