[OpenLayers-Users] Add labels above the lines.

[Alexandre Dubé]

I think I got it.

All vector layers but the one with labels are used by a SelectFeature 
control which is currently active, which makes all the other layers 
always on top. Deactivate the control and you'll that the labels will be 
put on top.

To fix this, you could try adding your labels layer in the SelectFeature 
control as well and behave accordingly if a user click on a label. I 
don't really see any other way to have your labels on top as long as 
this control is active.

Tell me how that sounds.
