Canon 5D + 580EX

I'm using a Canon 5D with a 580EX flash and the 2nd (rear) curtain
sync does not work. I've RTFM on both, checked all the settings, and
it doesn't work. I was planning to use the flash mostly in Av mode
taking advantage of the pre-flash when appropriate... tried other
modes for testing w/out success.

(There isn't a documented curtain sync selection in the 580ex so that
isn't [shouldn't be] the problem.)

Any ideas from owners of both?

The flash settings will override the camera settings. Don't know if
that's useful.
