Need details.... what slave mode? That sounds rather wrong, SB-700 should be Remote mode if the Commander is used.
"All other settings same" sounds wrong. For commander use, the SB-700 is in Remote mode, and ALL SETTINGS (except group and channel) are in the Commander menu. None on the flash.
You mentioned radio triggers. That sounds very wrong with the Commander. Cannot mix manual gear with Commander gear.
Need details, better description, specifics of what you are trying to do?
To use the Commander, put the radio triggers up in a drawer. Set SB-700 to Remote mode (not SU-4 slave mode).
By slave, I meant remote. My settings are on, remote, master. If it's not On or Master, it's "slave" to me.

And by all other settings the same, I mean camera settings. Shutter, ISO, aperture. I had the camera in commander mode, using the on-board flash to trigger the SB-700 which was off camera, and the only mention of radio triggers was because I need to get fresh AAA batteries for them so I can quit having to mess with this commander crap.
Basically, I was trying to get the same light output from the flash off-camera as I was getting ON-camera. Figured out the modeling flash was tricking the SB700 into firing a little early, and changed some other setting inside the camera menu, still not sure what I did, but got it all working somewhat normally. Need to test a bit more (and still need to get those AAA batteries, as RF triggers are much easier).
