Just for the record… I’m using IE7 and it creates an error message that reads:
Line: 176
Char: 290
Error: Access denied
Code: 0
This is followed by my URL that ends in wordpress/wp-admin/post-new.php
Also for the record: the WordPress community is great and I’m really glad I found it! I’m convinced the problem is with IE7. It’s notorious for messing things up.
