LW 5 will only run using Java 1.6. That means only mac osx intel users running leopard 10.5 can run the beta 5. If you have an earlier osx then you are limited. With OSX 10.4 you are limited to LW 4.18. Only mac intel users can use LW 5 because Java 1.6 for mac is in 64 bit technology.
Please do NOT double-post, we are not blind. We do see all posts. duh !

You will see from the LW download page only Leopard users are shown. Get your version from here
