Thanks.

I agree that that approach - simple zoom to a point - makes the most
sense, but couldn't make it happen.

I've attempted, unsuccessfully, to deal with this both through InvokeURL
and as a separate widget (not really sure what I'm doing, though).
The approach I'm trying to use is an 'OnClick' that fires the javascript
function to zoom to point.
I've tried to use some of the functions from the ZoomXXX widgets, but
there was never any communication between the task pane and the map.
Firebug (firefox extension) would always report that 'Fusion', or some
related function, was not defined.
So, I tried including various files, but was never successful at getting
task pane and map to talk to each other.
