I am trying to upload several HJ files (20mb each) but every time I go to upload two or more at a time (never more than 4 at once) the "Manage Attachment" window will, after a period of time, go blank, say "page cannot be displayed", or "You are not logged in or you do not have permission to access this page..." . Is something wrong or do I just have to upload them one at a time? I don't ever remember it being this way in the past. I am using Firefox 3.0.1.
