I am testing this and discovered some issues.

Suppose a page teaser is edited ..for instance the color of the text is changed to blue from black...

Newsflash will display both the black version and then followed by the blue version. When displaying the blue version , teh display box ( the default light brown box ) will be overlayed with anotehr brown box containing the blue version text but this box is shifted downward by a few pixel,

The result is that when it transition from black to blue text, one can see two box overlayed on one another.
