=========
The disappearing graphic when style is set to line appears to be a "feature" 
built into the MC engine. On MC 2.4.3, Win XP pro, I tried setting the style 
to "line" of a variety of graphic objects and indeed some of them disappear. 
They display if the style property is set to another value, such as regular. 
The same behavior occurs if a graphic object line is drawn, and then the 
script 

set the style of myGraphic to the style of thelineGraphic 

So, you'll have to evaluate this usage on an object-by-object basis to 
determine if you can use it for your particular app.
