Is it just me, or are all of the demos broken when using Flash 10 in OS X against v2.2.0 Beta 5? I get stuck on "uploading..." in each and every one of them. Works fine for me in Windows though.

demos: http://demo.swfupload.org/v220beta5/
browser: Firefox 3.0.6
flash: 10.0.12
os: OS X 10.5.6

thanks,
Chris
