Other widgets had this problem at a point. It was resolve by clearing 
the NAV_CMD like you did. Widgets that submit the page, but don't use 
the NAV_CMD parameter have to clear it before submitting. If you look in 
the WMSBrowser widget for example, it clears the NAV_CMD on every page 
submit like this:
         {$this->mszHTMLForm}.NAV_CMD.value = "";

This should be enough to deactivate the other Navigation tools. Let us 
know if you have any problem with this.
