Congratulations to the Prototype team for [rolling out Prototype v1.5.1](http://www.prototypejs.org/2007/5/1/prototype-1-5-1-released)! :D
Sadly, the current stable version of [Scriptaculous]() (v.1.7.0) is **not** compatible. In Safari, calling any Effect will fill the Javascript console with an infinite number of “Maximum call stack size exceeded.” warnings.
You’ll need to run the [Scriptaculous v1.7.1 beta 2](http://mir.aculo.us/2007/4/28/script-aculo-us-1-7-1-beta-2-for-your-download-pleasure) to avoid this issue until a new stable version comes out.
