[mapserver-users] imgbox works on Netscape but not Internet Explorer

[Michael Hearne]

I have a similar, if much less reproducible, problem.  I've got one
mapserver app where the 'Pan' mode doesn't work in IE, but 'Zoom Out'
and 'Zoom In' do.  Everything works just fine in Netscape.

Is there any difference in the way that IE handles form variables that
would cause this behavior?
