The current version of 1Password (2.9.31) has a compatibility problem with Safari in Snow Leopard, which by default runs in 64-bit mode. While 1Password 2.9.31 reportedly works normally in all other Web browsers under Snow Leopard, if you want to use it in Safari you'll either have to run Safari in 32-bit mode or first upgrade to the Agile Keychain and then upgrade to the 1Password 3 beta. To learn more, read Tonya Engst's TidBITS article, "Getting 1Password Working in Snow Leopard." For background information, on the entire 32-bit/64-bit/Input Manager problem, see Kevin Ballard's in-depth blog post, 1Password extension loading in Snow Leopard.
