[Chameleon] clear NAV_CMD

[Jesse Cleary]

Hi folks

I'm working on a very simple Chameleon based map with onmouseover and 
onclick functionality using a customization of the MapTips widget.  
Because of the onClick bit, my ZoomIn and ZoomOut widgets are presenting 
a problem.  Because they remain active after the map refreshes, a user's 
onClick action to get a MapTip also activates the selected widget asugin 
another refresh and not the desired onclick event.  I've tried to clear 
the NAV_CMD variable in my custom MapTips JS but I can't get that code 
fired ahead of the Zoom actions.  I'm using the scale zoom in the 
interim which provides a less desirable zoom function.

Any ideas on how to clear the NAV_CMD variable and/or de-select the Zoom 
widgets after refresh without tinkering with the base Zoom widget code?  
The base code powers several other Chameleon apps that I don't want this 
fix applied to.  Thanks for any ideas you can suggest...
