Since AOL for Mac OS X (v 10.3.7) is over 2 years old, the application is very outdated. The problems with AOL first started with Tiger when the program would crash every time you try to quit.
Then when AOL updated their member directory and moved it to the web, the program crashes anytime you try and view a profile generated from AIM. This is mainly due to the outdated Netscape browser used in the AOL application.
I can view mail under Leopard, but the Preferences crash the program. AOL now presents a message about Leopard regarding the inability to read mail, preference window crashing, attachment button missing from mail, etc.
It seems AOL abandoned the Mac years ago since the Application is so outdated.
