Hi Jennifer,

Well I'm not exactly a developer either ha, but I have a couple 
questions.  Did you install the same versions of MS4W and Chameleon that 
your application was running on?  just curious as to what versions you 
are using.  Also, do the Chameleon sample applications work?  e.g. 
http://127.0.0.1/chameleon/samples/sample_other.phtml (contains a 
TrueNorth widget)
