I've been trying to get the Demo working in IE10 on Win 8 Pro and the editor is simply never visible. It works perfectly in FF v 22.
The things I have tried so far:
1. Tested the Demo using every available combination of Browser Mode and Document Mode:
Browsers Modes: IE10, IE 10 Compatability, IE 9, IE 8, IE 7
Document Modes: Standards, Quirks, IE 9 Standards, IE 8 Standards, IE 7 Standards
2. Added http://*.ckeditor.com to the list if IE trusted sites and temporarily set the security level for trusted sites to the lowest possible.
Points of note:
1. If the Document Mode is sufficiently low then you can see everything that would normally be hidden until the relevent menu item is chosen (presumably showing and hiding of the <section class="demo-content" ....> parts). At that point the inline editor works fine but I still can't see the standard or full editors. It's clear where they should be but there's nothing there, not even an empty grey box for example.
2. In fact on the demo page the entire left side menu, Most Wanted, User Interface, etc. is broken. The relevant parts simply aren't not being hidden, even in IE10, Quirks mode etc. you can see all menu items in the list item cascade rather than just those under the currently selected top level menu item. It's as if IE cannot cope with the CSS / Java or whatever mechanism you are using to show / hide elements.
My initial interest was so as to be able to use this project:
Which uses a modified version of CKEditor, pretty certain it's pre-4 base code. Based on what I've read and that the project uses a WebBrowser control in Visual Studio then I can imagine pre-4 code not working in IE10 but when the Demo failed to work as well I started to get very confused.
So, one problem at a time, first I'd like to prove the Demo of v4 can work in IE 10 on my PC then once I know that CKEditor can work I can worry about that project.
Thanks in advance,
