It appears that the colorbox popup is not behaving correctly in IE8 on some operating systems due to conflicts in the jquery library. Consequently we are recommending that you remove the code and revert to the standard login screens. To revert simply delete these lines from your layout.tpl file in each template you are using <!-- colorbox for login --> <link media="screen" rel="stylesheet" href="templates/{$smarty.const.MAIN_TEMPLATE}/colorbox/colorbox.css" /> <script src="templates/{$smarty.const.MAIN_TEMPLATE}/colorbox/jquery.colorbox.js"></script> and a little further down {if $body != 'user/userlogin.tpl' && $body != 'user/userjoin.tpl' && $body != 'user/useraccountmodify.tpl'} {include file='ajax-login.tpl'} {/if} you may also remove the file ajax-login.tpl and the folder called colorbox if you wish.
