Hello,
The code <img src="<?php echo SITE_IMAGE_PATH; ?>/file_icons/sprite_48px.png" style="width: 1px; height:1px; position: absolute; top: -99999px;"/> on account_home.html was causing a blank screen on the file manager using Safari 5.1.7 for windows. I'm not sure why, but removing it fixed the problem.
