I've coded a 'div' element with a style property 'background-color' that surrounds a 'div' element with a 'border' property - in order to change the background-color via the "Text Background Color" button in the Blogger Compose Interface.
In Firefox 3.8 and earlier - it worked (as well as in early Chrome versions).
Now, when the element is high-lighted, and the "Text Background Color" button is employed - the Compose Interface simply erases the 'background-color' property from the 'div' element in the html.
I believe the fix is to add a 'Change Background Color' button to the Compose Interface menu.
Thanks for your help,
