I attempted to upgrade to 2.7 RC 2 the tools>upgrade However when I went to wp-admin/post-new.php to add a new post and click on the tab, 'Visual' no cursor shows up and if I click and drag I see the HTML tag for line break </br>. However this HTML tag is only present when I click and drag.
If I edit a post and click on the 'Visual' tab I see no text. However if I click and drag I will see the text along with the HTML tags. this bug makes it impossible for me to add any texts and I am disappointed that this issue has not fixed.
I have done some initial testing with different browsers and all produce the same result but the cursor being visable in Safari.
It is my hope that this error will be fixed when 2.7 is finally released.
