"Upload a Media button"... hangs on "Configuration" check screen.

When editing and trying to upload an image using the Media Manager buttons, a screen comes up and stays, with a check mark next to Configuration Check and does nothing from that point on "hangs up" on that screen. (attached screen shot)

The image itself doesn't matter, you can even try it with an image already in the Media Manager. What seems to matter is trying to add the image to a blog that has 'already been published', when going back in to edit the blog and add an image after the blog is created the first time.

Going through other posts in this forum, image uploading seems to be an issue with quite a few users. Here is the old thread I posted to: #91537: Picture Uploading Hanging On Configuration Again

This is an 'intermittent problem' across all browsers, Windows 7 and 8 and multilple computers in different locations. Sometimes it works, sometimes it doesn't.

Try this:

1. Create a post in any Category, just make the post text, use some html in the post like h2 for example, then publish. It works and looks just fine. Log off.

2. Login and go back and try to edit the post by adding an image in the text area. This is when the Configuration Screen comes up for me.

I've uploaded the access info also. I'm wondering if it is in the settings.. What we are trying to do with this blog is have a simple 'one-way' blog. A single blogger posting, that's all. No team blogging, no commenting. Will you check the settings and make sure I have it setup to accomplish this?

Thank you for your continued support.
