ckEditor links can't be saved on IE

[Dainis Abols]

I have a strang bug(?) with ckeditor; a project, I work with, has ckEditor as texteditor and works fine on all browsers, except on IE, where, when hyperlink option is chose, it has some extra fields:

Now, that wouldn't be the biggest problem, if the OK and CANCEL buttons would work - they don't.

PS: I removed those options on link.js. Now CANCEL works, but OK doesn't. Meaning, I can press it like a 1000 times, nothing happens. Not even an error message.

1. what you see are all link panels that are displayed (one at a time) when you change link type dropdown.
2. Most likely you see this result because JS error is thrown. Please check IE dev-tools console.
3. Which IE and CKEditor version are we talking about here? CKEditor supports IE11 from version 4.3. If you are using any version below that number this might be the reason.
4. I'm not familiar with "Insert crosslink". This is something you may have added on your own. If that is the case this may be another reason why error is thrown (errors in custom change).
5. If you are using any custom plugins, please try using the editor without them to exclude possibility that custom plugin is doing that.

Please check what I have written and provide necessary information.

Hello, yes, the crosslink option is added, but it does not change the outcome when removed.

And also yes, this occures with ckeditor 4.2 on IE11. Is there a small fix available? Because, since I'm new to the project and have limited information on what additional plugins and modifications are made, I do not risk upgrading it yet.

Edit: the console gave me Unable to get property 'collapsed' of undefined or null reference

Unfortunately IE11 required a lot of patches, because it has been changed significantly comparing to IE10. It was a bigger change for us than between IE11 and Edge actually. So the only option I can see is upgrading CKEditor.
