Snap Tool not making features coincident

Hi,
I've been trying out the snap tool in the Editing toolbox (I'm using ArcGIS 10.0 sp4) to try to get a polygon to be coincident with a line feature, but it's not working.
I got inspired to use the tool after watching Python Essentials in ArcGIS (jump to 21:38) http://video.arcgis.com/watch/74/python-essentials-in-arcgis-i-_dash_-an-introduction and I read through the Help - http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Snap/001v00000007000000/ and I found this arcticle on using the Snap tool - http://www.esri.com/news/arcwatch/0412/use-the-snap-geoprocessing-tool-to-automate-editing.html

I have a single polygon in a feature class in a FGDB and a line feature class. I set the input features as the polygon, the line feature class as the Snap Environment and I set the type as Edge and a distance of 100 meters.  I run the tool and the polygon is modified but it is not coincident with the line.
Oddly, both feature classes are projected in UTM Zone 10N, NAD83 but when I enter the distance, unless I enter metres, it defaults to Unknown.

See the attached image to follow what I'm doing and the result.
Anyone else had these problems?  Any suggestions? anyone had this tool work as per the documentation?
Thanks for your help
