Newest C5 and Internet Explorer 9. I tried to "Edit/Properties/Custom Attributes" and nothing shows up except page name. When I try to change it, a huge dialog box is generated with all the code of the page in edit mode.

I move over to Firefox. No problems. All the attributes are visible, I can change them and everything works as expected.

I don't rememember this happening in previous versions of C5.

Please, no suggestions about "Only use firefox" or whatever. Obviously, there is a bug and telling my C5 users they have to move to FF for development is not an option. It used to work.

Thanks,
Chris
