Hi, I happen to find that when using category feature, the url link for dataset document is no longer displayed. The link appears as ("more...") in the window that popups when click on "i" mark. Is this a bug (v6.1)? -- (Bob) Yunyue YU Code 971, Goddard Space Flight Center Greenbelt, MD 20771 (301)614-6850 yuy@nemo.gsfc.nasa.gov
