Some Models Cannot Have a Background Gradient

This information was provided by Claris Corporation on 16 March 1998, and incorporated into Apple Computer's Tech Info Library.
It is not possible to apply a gradient fill to some Models even though it is possible to choose a color fill.

Models which cannot have a gradient fill are:
Timeline
Table

ClarisImpact will beep at you if you attempt to fill one of these Models with a gradient. All other Models will allow gradient fills.

Workaround:
Change your Timeline to a transparent fill (first choice on the pattern palette) and then draw a rectangle that matches the dimensions of the Timeline. Fill the rectangle with a gradient and send it behind the Timeline.
