I had this problem too (excuse me for my bad english..., but i solved the problem with this..
Look in account_manage foor this part:
<!doctype html public "-//W3C//DTD HTML 4.01 Transitional//EN">
<html <?php echo HTML_PARAMS; ?>>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=<?php echo CHARSET; ?>">
<title><?php echo TITLE; ?></title>
add directly after:
<base href="<?php echo (($request_type == 'SSL') ? HTTPS_SERVER : HTTP_SERVER) . DIR_WS_CATALOG; ?>">
This wil solve the problem, i think. (you wille have solved the problem already but this is for anybode with the same problem...)
