Bill, just trying Chrome to see if I have more luck uploading an image. Just a post of a project I am starting today.
Looks as if the problem was with IE 10 ? No problems with Google Chrome !
I don't have IE 10 so I can't test it. I bought the Windows 8 upgrade but for some reason it will not install on my system. Perhaps it is some built-in pop-up blocker or something in IE 10 that is causing the problem. The page does refresh after uploading an image.
Try something else out...in IE 10 browse to the image you want to upload but don't select the Upload button. The image should still upload automatically. The disadvantage is that you can only place 1 image per post that way.
