Configs in eDrawings

I have an assembly in which I have 3 configs, Default, Upper,and Lower.
Default shows everything while Upper shows only the uppercomponents and likewise for Lower. In the Upper and Lower configs ,I hid (vs. suppress) components I didn't want to see. This allworks as expected. When I saved it as an eDrawing (saving allconfigs within), there were several issues I can't figure out.First, in the eDrawings tree there are 3 thumbnail icons of eachconfig. The thumbnails look like what the view should be. When Iclick on any of them, nothing happens. I have to click on DisplayStates to change the view in the graphics window. Second, there are5 Display States listed, 3 of which show all the components. Also,when I click on the DS that shows the Lower, it looks like itshould. But when I click on the other DS for the Upper, there isone component still visible that should be only in the Lower. Anyideas what I'm doing wrong? I'm using eDrawings Pro 2008.SolidworksEdrawings
