I recently had a project (website) to build and again i've faced the MAC OS mouse wheel issue (which i'm sure all of you come to from time to time).
Yeap, there're some workarounds like the one that pixelbreaker did or the one that libspark did, but they don't work properly (for eg in os leopard). So, after hours spent to find a clear solution i decided to build my own lib which would allow the browser's native scrollbars usage instead of trying to solve those issues. And now that the lib is released, i just wanted to share with you; probably some of you find it useful.
Hope it helps your devs.



Project: SWFSize lib
Language: as3 + js
Licence: open source
Requires Flex Framework: No
Requires AIR Runtime: No
Project Owner: Julius Loa (me
Description: SWFSize is a small (really small) library for Adobe Flash technology that works in collaboration with SWFObject and provides control over the swf's container metrics. By controlling the swf’s container metrics SWFSize gives you the ability to solve the MAC OS mouse wheel issue once and for all; don’t use workarounds - use the browser's native scrollbars instead.
You can view the samples/get source/docs at the project's home page.
