Navigation is not happened from Google widget location widget to another mashup

Hi,

We want navigate to another mash up on double click of selected location of google map widget.

1) On double click on tree widget we want to highlight location  on map widget, It is working fine

2) On double click on map selected location navigate to another mashup. This is also working fine but fails below scenario

When we try to achieve both together is not happening, what we found is to achieve above functionality we had to checked (Show Selection Marker check box). The moment we checked that navigation functionality from google widget to another mash up get stopped.
