Is anyone else experiencing this? Trying to ‘FillObject’ a subtool with ‘Flat Color’ from Standard Materials is not working. If you ‘FillObject’ with a different material, it works, but if you then go to fill that subtool with the Flat Color, it just reverts to the Red Wax material. Not only that, but after installing 4R2, this also no longer works in 4.0.
It’s never ‘worked’. 
Flat Color is a special material in that if you fill an object with it, that object will display the selected material. Effectively you are removing any previously embedded material and reverting to the default behaviour.
HTH,
Thanks Marcus! I know that it is how you reset a material, but I could have sworn though, on more than one occasion, that I was able to fill with the Flat Color and it stayed filled.
