Canon 580ex flash (as slave) fires after shutter closes - help solving this problem?

Hi,

I have the 580 ex and have been trying to use it as a slave. I have the canon 600 ex-rt on camera set up as an optical master and then the 580 as a slave.

The shutter opens, the 600 fires, the shutter closes (even during a longer exposure) and then after it closes the 580 fires.

Any ideas why? I ended up using the 600 as a master and my older canon 420 (or something like that) as a slave and it worked fine.

Thanks for your help

Micah
