I experience a similar problem. My blog is located at http://mysite.com/blog. When I upload the images it goes to the correct location however when I drag and drop the image into the post the link is http://mysite.com/wp-content/uploads….. and not http://mysite.com/blog/wp-content/uploads….. My settings are set properly so I’m assuming it’s a bug.
I’m having a similar issue. I have two users on my system, http://jokerr.com, admin and myself and I cannot login with either account. I ‘ve tried using the “sexygeekgirl” wp-login file with no luck. Then like you I tried copying a fresh new wp-login.php file in its place. Nada. When going to /wp-login.php or /wp-admin all I get is a blank page…. Don’t know if it helps but I’m running WordPress 1.5.2 on Apache 1.3.x
