Well, according to the link, standard slave flashes won't necessarily work with digital cameras. A lot of digital cameras flash more than once when you take a picture. The first flash allows the camera to adjust itself (white balance, exposure, etc.) and then the second flash actually takes the picture. Also, if your camera has red-eye reduction, this also triggers a series of "pre-flashes" to cause the eyes' pupils to close before the final, picture-taking flash. A slave flash needs to "know" which flash is the actual picture-taking flash and fire at the right time. A regular slave flash for a film camera will have fired and gone dark before the camera actually takes the picture. Slave flashes for digital cameras know the difference between the pre-flashes and the brighter "picture taking" flash and fire at the correct time.
Geez, I sound smart again. All because I did a google search. =)
P.S. You said you have a slave strobe for your 35mm, right? Have you tried using it with your digital? It should be easy enough to find out if it works for you.
