#HILIGHT Problem
The alpha>0 option is still glowing the previous layer because its non-zero
alpha pixels are accumulated into the next layer's alpha. If you want to
inhibit this, download the NOALPH.ZIP file from DL1, which contains NOALPH.IXP.
Put that right behind the layer that you want to hilight, and it'll inhibit the
alpha from previous layers from being passed down the chain.
