Safari 5.1.5 Update Improves 32-bit Stability

Following closely after the release of Safari 5.1.4, Apple released version 5.1.5 of its Web browser to address difficulties a number of users have had opening the program in 32-bit mode. Apple's latest hardware and software support has been for 64-bit code, but in order to support older plug-ins and for other compatibility reasons Apple includes a 32-bit binary for its Safari Web browser.

Apparently a significant number of Web sites would not run properly when people ran the 32-bit version of Safari, and this update addresses this problem. In addition, the update includes a couple of stability fixes for people running OS X 10.6.8 and Windows.
