Hate to keep doing this you, Pierre...

I love the capability to have the Headers of particular Fields be set to a specified color and this feature appears to work flawlessly EXCEPT when that Field becomes FOCUSED in the Grid. IQ appears to re-draw the Column Header (in anticipation of emphasizing the currently active column?) to the Default Header Color. This isn't that big of a deal when you set the Grid Cells to be colored as well, but I find that be overkill in most circumstances.
