I wouldn't assume that because everything worked fine in hosted mode
that web mode will work perfectly. There can be hiccups every now and
then!
You didn't say which OS/browser you were running, but one of the first
things to try is to run web mode under firefox/firebug and see if
there are some exceptions that might be short-circuiting your code.
There is a problem in the demo showing and hiding Polygons that I've
never been able to get to the bottom of, but that problem occurs in
both hosted and web mode.
