Hi,
I am having some speed issues displaying markers thousands of markers with an InMemoryMarkerOverlay as such I have broken the zoom levels into 2 peices (Highlight and Details) but need a way to have a the overlayswitcher when checked remove 2 layers. The Highlight for zoom levels 1-14 and the details for zomm levels 15-20. (which is very fast and works well.) Is there a way to have the OverlaySwitcher when checked / unchecked change 2 (turn off/on both layers (details and Highlight?) inmemorymarkeroverlays?
Thanks in advance!
