LayerSwitcher<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV dir=ltr>
<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>is it possbile with the LayerSwitcher control to select a layer (I don't
mean turn invisible) which I then could use to change it opacity. The
opacity part works well from the examples but I want to do this per layer I
select.</DIV>
<DIV> </DIV>
<DIV>Best regards,</DIV>
