Hello, I can't reproduce the issue as you can see on the enclosed gif image:

Could you provide minimal CKEditor4 demo with the issue e.g. using https://codepen.io ?

What browser did you test?
I tested in:

• Browser: Internet Explorer 11.0.9600.19463
• OS: Windows 8.1

and:

• Browser: Internet Explorer 11.950.17134.0
• OS: Windows 10

I tested again with a custom minimal basic build:

On Windows 10 it works in Microsoft Edge 42.17134.1.0 but not in Internet Explorer.

Internet Explorer:

Microsoft Edge:

I cannot use codepen in Internet Explorer:

Works fine for me on Windows 8.1 IE 11.0.9600.18953 and Windows 10 IE 11.785.16299.0. You can use any other tool like e.g. https://jsbin.com/ which should work with IE11.

Does the downloaded index.html from sample folder work for you?
I can confirm that it works in jsbin.com but not the local executed demo from the samples folder.
See: https://jsbin.com/fadalemaka/1/edit?html,js,output
Any other ideas?

Yes, it works fine when opening samples/index.html file for Edge and IE11. @Dumluregn could you try to reproduce the issue? I could miss something but works fine for me, also it's unlikely that such an issue would pass our testing phase.

Ah! It works when executing from C:\ckeditor\samples\index.html but not in my virtual machine from path \Mac\Home\Desktop\ckeditor\samples\index.html (parallels shared folder).

So, it may seem like there are some missing static files when using a shared folder for VM, but it's rather 3rd party software issue, not CKEditor4 itself. Due that I'm closing the issue, but if you still consider it as a CKE4 bug @Tomcraft1980, please, provide us feedback so we can reopen the issue again.
