if you run the following code at Firefox browser, it works fine. However, if you run it at IE7 you will notice that when you click on any link, a new page will be open which is not correct. So, how can I fix this problem in IE7? I want any link open within the frame, NOT a new page.

//Here is the code:

<html>
<head>
<title>Testing</title>
</head>
<body>
<td height="450">
<base target="I1"/>
</td>
<table width="490" border="1" align="center">
<td> <iframe src="file1.htm" name="I1" width="350" height="290"
frameborder="0">
</iframe></td>
<tr>
<tr>
</tr>
<td >
<a href="file1.htm">item1
</a>
</td>
<td>
<a href="file2.htm">item2
</a>
</td>
<td width="102">
<a href="file3.htm">item3
</a>
</td>
<td>
<a href="file4.htm">item4
</a>
</td>
</tr>
</table>
</body>
</html>
