I added a very simple navigation bar to the InfoWindow on MouseOver sample.On load, the featureLayer mouseOver events work fine. When navigation is activated (by any tool), the mouseOver events fail to work. Once navigation is deactivated, the MouseOver events work again.Test case:

<!--
This sample shows you how to display an InfoWindow on a mouse over ("map tips").
The 46 South Carolina counties are all fetched from the server using the
'snapshot' mode and drawn clientside. As the mouse moves over a county,
an infoWindow will show as a 'map tip'.

Is there a way to avoid this?Thanks,Glen
