IE7 crashes in Theme Selector. In new version of theme/index.php (index.php,v 1.32.2.1 2007/04/20 07:50:29) IE7 stops responding, previous version (v 1.32 2007/02/07 07:34:55) works OK. The only reason I can see is that new version is using <OBJECT> tags and old version had <IFRAME> tags.
Firefox has no problems with new version.
