[OpenLayers-Users] Async layer loading

[Dragan Podvezanec]

Hi all.

I have map with 3 wms layers. 
Two of them are overlays. One overlay (let's say layer A) is a
non-transparent JPEG (aerial imagery) from slow WMS server. Layer B is
transparent PNG layer from fast WMS server, and it is always loaded faster
than layer A. since layer A is not transparent, it has to be "below" layer
B.
But what happens now, that layer B doesn't show before layer A, and that can
take some long unnecessary time. Can I somehow "force" layer B to show, even
if layer A still isn't loaded?
