Thanks for the detailed & accurate instructions. 

This does prevent the ISO from being raised...  But like you mentioned in the follow up post it causes the ISO to never be raised so in essence disables auto-ISO.  Also since it is in commander mode you get the double flash that sends signals to other remotes...

You have figured out that this so called "work around" is a bad idea . A much better solution is to set up one of the the Mode dial U1 or U2 for flash photography. I set my U2 up for flash in Manual mode and 400 ISO and f5.6, with the LCD light set to be on. I may be the miniority, but I actually prefer the way Nikon has changed how flash works with Auto ISO because it works better for fill flash outdoors when the subjects face is shaded and also works better for balancing ambient light and flash indoors when their window light. It's nice that Nikon added the U1, U2 custom settings on the mode dial to make these changes easy and fast.

It would have been nicer if they'd added the option to raise ISO first or raise flash power first when auto ISO is set with flash. That way you wouldn't have to waste your custom settings on flash vs no flash,

You think using a  custom User setting for flash is a waste of a User setting? Are you serious? That is exactly what the User settings are for. They make it easy to do a global change with a flick of the Mode dial. Your D90 has no User Settings on the Mode dial at all. How do you ever get by Sammy?

nor would you get bitten if you forgot to change the setting when going between flash and no flash. Someone would no doubt complain about yet another setting added to the menu, but I think this one would be well worth another slot!

Knowing if I am in flash mode or not has not been a problem for me yet, but if it is a problem for you, then here is a hint for you:

If you see a flash when you take the shot, then you are in flash mode!

Since fill flash as a default is Nikon's new flash implementation, (which I agree with, BTW),  you may want to reconsider beating this flash issue to death with every new Nikon DSLR introduction Sammy,  'cause it's not going back to the old way, no matter how much you rant and stomp your feet. Instead take a course in flash photography, but don't be surprised if they tell you to use a fixed ISO and take your camera out of "green mode"!
