[OpenLayers-Users] problem: IE loses mouse zoom capability when overlay layers are all unselected

[JK Chen]

Hi,

My app has two overlay layers: one for markers one for shapes, both sitting on top of base maps which consists of 4 Google maps and two wms maps.

Whenever I unselect all of the overlay layers, in IE, all of mouse zoom capability are gone. This includes mouse wheel in and out, all gone. However, the zoom bar + and - continue to function.

In Firefox, zoom functionality works just fine, including mouse wheel.

Any idea?

Thanks for your help.

JK
