Hello, First at all I wish to acknowledge the people who help me with this problem, though finally, I have to contact the NMNH wen page administrator to solve it. Second, I post this for the existing chance that somebody have the same trouble in a near future (with this or some related item). The problem resides in the browser (MS Internet Explorer 5.0) that was unable to handle the gopher system used in many databases. The solution is to download a partial upgrade (Service Pack 1) from Microsoft's site wich overcomes the problem. Netscape seems not to have this fault, and works fine "as is".
