I am using Mac OS 10.4.3 and my limewire was working fine until I upgraded to the 4.9 version. Since then every time I try to cancel the download of a song I have already chosen, the program stops responding for 10-15 minutes. And if I select many songs at the same time to cancel I might as well take a nap because that takes hours. Has anyone experienced similar problems or have a suggestion how I can fix this?
