Fill Color and Stroke Color option not working... - Macromedia Flash

I am a faculty member at American River College who needs a word or two on how
Flash CS3 works.

Specifically, how do I get back the option to add fill color to an oval
drawing that I have made in Flash CS3? It appears that I have flipped a
setting that makes that seemingly simple option unavailable.

I have several other documents where I have added fill color without a
problem; however, as of this morning CS3 will not allow me do add such. When I
open Flash, I draw on the Stage, the outline color is usually green, no matter
what color I select for as Stroke Color and Flash will not allow me to change
the Fill Color. I make a selection and nothing happens (just moments ago I
opted for red as the Fill Color and the Fill remains white).

Is there a setting in Flash, that a rookie like yours truly could activated by
accident?

Please help.
