z-index

Hi,

Maybe a silly question, but it seems like z-indexing works backwards in 
amaya.  If I view my webpage in firefox, opera, etc.  everything appears 
fine (i.e. item with z-index of larger number will appear over item having 
a smaller z-index).  However, in Amaya, the order is reversed.  Am I doing 
something wrong?

I can provide source code of my page if it helps (it's pretty small.)

Thanks,

Mark.
