I tried your example, and I'm getting an error appearing in the Messages
window:
The specified setting for the option SliderBoxOptions, Appearance
cannot be used.
This refers, I believe, just to the value "" of a.
More importantly, I'm just seeing three ordinary, rectangular sliders.
Yet I do see the anticipated effect in the screen shot you linked in
your reply.
Something very peculiar is going on!
My version is
$Version
6.0 for Microsoft Windows (32-bit) (June 19, 2007)
which is what is otherwise known as 6.0.1.
