I thought it was working, but on testing on my own application it was still going wrong. It took me a while, but now i found a reproducable situation. It appears that there is a difference between Firefox and IE11. I have enclosed screenshots of the before and after paste on Firefox 33.1 and IE 11.0.9600. Also the worddocument is enclosed.
The test-url is http://dojo.telerik.com/uVed/2
You can see in firefox that the pasted text is completely different and more important it is pasted outside the editor, so it can not be accessed anymore.
Can you reproduce this also and if so, how can i fix this?
