Pascal -

Thanks!  That did the trick.  It didn't occur to me to think of that sort of
problem, and I appreciate the insight.  It's working fine now.

The strange thing is that this method:

myLayer = DynAPI.document.all['mapLayer']

should work.. maybe the problem you'r having is that you name your variable
also mapLayer (the same as the inline layer) I think IE chokes on that, so
try using another name for it.
