[OpenLayers-Users] Problem with pop-up rendering and layer overlay in Openlayers 2.7

[Subha Ramakrishnan]

Hi,

I've upgraded to Openlayers 2.7 recently. I have a problem with showing 
the pop-up with point layers.

I am using Google Physical as base map and when i render a point layer( 
features drawn using OpenLayers) overlaid on the base map, the z-index 
of the layer div ("OpenLayers.Layer.Vector_some_number") sometimes goes 
upto 1206 (the maximum I've observed till now).
Where as, the z-index of the pop up is 751 (OpenLayers FramedCloud pop up).
So, the features appear on the pop up and i can't access links on the 
pop up.

Also, when i have multiple layers overlaid on the map, a few layers 
which are not currently the top most layer, have a higher z-index value 
and so the features belonging to this layer appears to be active.

 From my observation, the z-index of the "div" is calculated 
automatically.Is that correct?If so, what is it based on?

Does anyone know a solution to show the pop up above the layer features? 
I didn't face this problem with the previous version of OpenLayers that 
i was using.

Thanks for the help.

Regards,
Subha
