Background image height in IE7 for A tag

[TMUK]

Hi,

I have observed a problem which could well be down to my code however,
I thought I'd ask here:

I should point out, I am testing in IE 7.0.6002.18005 (with DebugBar
5.4)

In implementing either IE8.js or IE9.js the height of my A tags seem
to get screwed after using javascript to change the class on the
parent DIV.

I've written a little test script to demonstrate: http://www.taximap.co.uk/test/ie7js.asp

Any help much appreciated, or is this a bug?

Cheers,

Mark

Is there any way you can simplify your test page? There is an awful lot
of CSS there.

IE7.js is not dynamic. If you change an element's properties using
javascript then there is no guarantee that those changes will be
reflected in CSS.
