I'm a new user to WordPress and my day to day browser is IE 7 Beta 2. Yesterday, I upgraded to the latest release of IE 7 (which was released yesterday morning). Here is what I'm experiencing using the rich text editor.
When I view the editor or click "Save and Continue", I get a bar along the top of my browser window warning me that unsafe content is being loaded (maybe something that is http instead of https being loaded).
I also get a JS error when I add a hyperlink to a page.
I don't expect updates to be made based on a beta browser but this is just a heads up.
Thanks for everthing though. I really like this site and the personality of the software. Good work.
