Works fine in FF - but with IE if you try to save a node that has uploaded images from the swfupload module it doesn't save and take you to a 'Access denied' page. If you don't try to upload any images with swfupload the node saves fine (even with the plugin active and available on the page), it only happens when some images have been uploaded...

My client is also having issues using Mac, but this may be related to the issue above?
