When I am stitching surfaces, the behavior doesn't seem to equal what is described in the online manual pages. For instance, I have two surface edges near each other. Using the stitch edges tool, I click on the outer edges of both and confirm with return. The gap between the two edges is bridged, and what appears to be one surface is created. However, they are still two surfaces. I can click on each one and the two are listed in the outliner. I guess I was under the impression that stitch would "weld" these two surfaces into one. What am I missing?

Thanks.
