[MS4W-Users] Same map displays layer on one page but fails on another

[Theobald, Charles]

I have a map that displays perfectly on one page, but when called from a second page fails to draw a critical layer.  The only difference is the mapsize; 200x120 on the first call, and 470 x 250 on the second.  The first call is on the site index page, hyperlinked to the second page, so the first will always be displayed first.  I'm also getting the error "loadForm(): Web application error. Not enough arguments for mapsize.", although the url calls the exact same .map file the only difference is the size.  
We never had this problem with version 4 of the mapserver on Linux, it's only occurring on a new host, windows 2008 R2.
Any suggestions would be appreciated.
