Google Maps API version 3 Marker manager Issue
<p>Open any location with a zoom level lets say 4, then Move to another location with a different zoom level lets say  8 then move another location with a different location with changed zoom level and then back to the starting position but this time with a different zoom level lets say 8, the marker is invisible at that zoom level. Why?
I have call markermanager refresh() method at that time, apply all the listeners zoom_changed, Center_changed, bounds_changed etc to refresh but not getting what I want.
At the time of marker creation in marker manager I have set the max and min zoom level value 3,17 i.e., max supported by marker manager.</p>
