I have downloaded and successfully installed Ifeffit-1.2.10-Mac10.4_PPC_horae66. But every time I click on athena, the X11 and aquaterm message appears, and regardless of my choice, Athena won't launch and will automatically quit! I downloaded X11 from Mac website and while installing, a message came up telling me that I have a later version already installed on my mac. But still, can't get Athena to work. I also downloaded and installed iXAFS.app. After clicking on the iXAFS icon, a window appears to specify the path to data and three icons to Athena, Artimis, etc, but clicking on the icons won't take me any where! Any insight would be greatly appreciated. Thanks, Hind ---------------------------- Hind A.
