[OpenLayers-Users] Popup Background Opacity/Transparent?

[Arnie Shore]

I hope I'm wrong on this, but I see no way to specify the popup 
background opacity separately from its contents.  (This doesn't apply to 
images in a popup, which I can't use here.)

That is, I'd like - in effect - the popup's background to be invisible, 
while its elements are fully visible.  Right now I see that the opacity 
factor applies to all its elements.  Confirmed?
