CKEditor v4.11.1.2
WB-Version 2.12.2 r379

Whenever I create a link in CKEditor, an extra space ( & nbsp; ) is added behind the word once the page is saved. It also makes a linebreak in the source code. This linebreak seems to be responsible for adding a space. If you look in the source code, there is no space. If you look at the page in your website, there is an extra space.

Magic!

Simple problem: I don't want that. :)
Now CKEditor consists of tons of directories and scripts, can anyone point me in the right direction where to look for the solution?
