Tab Menu display all contents at once in IE7&8

[jwally]

Hello,

it's about http://test.isxpm.com/index_test.php and dynamic loaded TabbedPanels with

http://test.isxpm.com/SpryAssets/ajax.js
and
http://http://test.isxpm.com/SpryAssets/ajax-dynamic-content.js

1.) It works in all browsers Firefox, Opera, Chrome and Safari, except IE7 and IE8.
I get the error :

UserAgent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; GTB6.4; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; Tablet PC 2.0; InfoPath.2; .NET CLR 3.5.30729; .NET CLR 3.0.30618)

2.) Even though I included two different .css files: http://test.isxpm.com/SpryAssets/SpryTabbedPanels_index.css and http://test.isxpm.com/SpryAssets/1/SpryTabbedPanels_isxpm.css located in two different folders, only the styling from SpryTabbedPanels_index.css will be applied for TabbedPanels. For TabbedPanelGroup the style from the second file applies, but only in Firefox and Opera.

These files will be loaded with ajax-dynamic-content:
http://test.isxpm.com/de/include/isxpm.inc.php
http://test.isxpm.com/de/include/isxpm2.inc.php
http://test.isxpm.com/de/include/isxpm3.inc.php
http://test.isxpm.com/de/include/isxpm4.inc.php
http://test.isxpm.com/de/include/isxpm5.inc.php
http://test.isxpm.com/de/include/isxpm6.inc.php

I'd like to have a different style for the loaded files with ajax-dynamic-content.

thanks for help
