When I try and add an image I am able to select it but as soon as I ask it to put it into my rich text editor I am asked to authenticate against my site again, I then have to reselect the image and then when I ask it to insert it into the rich text editor again I get a blank white screen. I have tested this on 3 machines, 1 Linux and 2 window machines which Firefox and safari and get the same result. I have verified the media-upload.php file is in wp-admin. Any advise on how to troubleshoot this would be appreciated. On my XP box I was able ot get it to throw an error for me (within Firefox). I get the error as soon as I select that I want to add an image from the rich text editor. Thank you!
