Internet Explorer 7 has trouble jumping to on-page anchor links when you code the page using the usual standards.  In other words, the page will validate and your code may be correct but IE fails to properly use the anchor.

For example, if your anchor code is like this:

<a href=#ALink">Jump to Target</a>

<a name="ALink">Target</a>

then IE7  may not properly jump to the target link.

I find the following addition fixes the issue:

<a href="#ALink">Jump to Target</a>

<a name="ALink" id="ALink">Target</a>
