Hi Dave- Just for completeness (and to test out our new support inquiry system), I'll respond to this message even though I think you are all set. > > Cancel that last message.

One of the reasons we had to have a separate chooser for Level II is to be able to select the station information. Older Level II data does not have any information in it about where in the world the data are valid. So, you could plot Denver's data over Albany, NY. By default, it sets the lat/lon/alt to 0,0,0, so if you have Reproject with new data turned on, it should plot it over Africa. If you do load in the data using the File Chooser, you can change the location of the data using the Properties dialog of the Data Source (right click on the Datasource in the Field Selector and select properties). Under the Properties tab (seems kinda redundant), there's a dropdown list that allows you to set the location. Unfortunately, I noticed it does not go off and reload any displays, so I'll put that on the list of things to do. > The plot control window includes the item: "Station: Re", confirming > that it didn't get the station data. > > There's a message in the bottom left corner of the blank North > American map that says "domain must be only spatial", but I don't > know how to act on that info, if in fact I can act on it. Hmm, I didn't get this, so I'm not sure what's going on. Which display type did you use? > I don't see anything else in the documentation that might give me a > lead. Am I missing something?
