I just tried it. Its working but it's moving at the speed of dial-up
for loading the pages. You may have to allow pop-ups for the website,
at least temporarily.

Here are the steps I used:
1. Website: http://seamless.usgs.gov/index.php
2. press: "View and Download United States Data"
3. wait - it took a long time to load this page, don't know why
4. Under Elevation, make sure NED Shaded Relief 1 arc second is checked,
also GTOP060 Color Shaded Relief is checked
5. under Downloads press: "Define Download Area by Coordinates"
6. In new window, enter box for coordinates. Replace SS.SS with 0
(that's a zero)
In the past I have found that if you add an area that is too large,
the system will hang.
I used a box 12 by 12 arc minutes.
7. press: "Add Area"
8. In new window: press "Modify Data Request"
9. wait, it's slow to load. There should be a progress bar at the
bottom of the page.
10. New window, scroll down and change ArcGrid to GeoTiff, make sure
NED 1 arc second is selected
11. Scroll to bottom of page and press: "Save Changes & Return to Summary"
12. wait - it's slow to load the page
13. Now back to the down load page, press "Download"
14 wait, New window, wait - My download didn't start automatically. I
had to press the "here" link to retrieve it
15. Then I get the pop-up to save the file to a location.
