Your co-workers are right. Maps in geographic coordinates (EPSG:4326) look like that. The further you get away from the equator, the more the map will be shrunk in latitudinal direction. This is not a bug, but a matter of choosing the appropriate map projection. > The GIS staff tell me that our data is projected in UTM 17N NAD83. The EPSG code for this projection is probably EPSG:26917. See http://spatialreference.org/ref/epsg/26917/ So the two things to change in your code is that you set the projection to EPSG:26917 instead of EPSG:4326, set units to "m" (meters), and provide the maxExtent in projected coordinates.
