Unfortunately, my test drive didn't get far, as I can't close any CKEditor dialog that I open (e.g. link, picture). The F12 tools report a lot of ""access denied"" errors. I can see the problem both on the 4.x demo page and in v3.6.6, which is still our production version (and has more IE11 problems, but I can understand that nobody will fix them for that old version). Haven't found the time to debug in deep until now, but that might be related with ""IE hacks"" no longer applying. Microsoft has changed the user agent to get rid of old hacks: http://www.nczonline.net/blog/2013/07/02/internet-explorer-11-dont-call-me-ie/ Testing IE11 is rather easy. The official ISO images of Windows 8.1 can be downloaded from: http://windows.microsoft.com/en-us/windows-8/preview-iso The product key is also mentioned on that page. Afterwards, it can be installed in VirtualBox, which requires a small patch, depending on its version: https://blogs.oracle.com/fatbloke/entry/using_virtualbox_to_test_drive **Edit:** I was able to reproduce this for Image, Link and Flash Dialogs . When you open one of these dialogs you get permission denied error. " Bug closed Normal UI : Dialogs 4.0 duplicate IE11
