Initially it was working ok, but as I was customizing website and templates it stopped working. Now when I click on File Browser button for image, it pops up as a new page, but I cannot access it. I can click on File Browser many times and it just keeps opening new windows that are not visible. It works fine in IE though. I tried reverting back to original skin and layout, but that had not effect. Is this a bug with CKEditor? What else can I do?

Thank you!
