I was trying to respond to a question, using IE version 11.0.31, the paste functionality does not paste anything in the text box. However; in Chrome it works fine.
To reproduce it:
1. Create a bug report but do not save it using IE
2. Now copy something from another page on IE
3. Try to paste it in the body of the bug report in IE
4. the paste will paste nothing or you will see still blank.
The above works well with Chrome.
I am an IE user as well, so I've seen this problem before (and it has plagued me for 1+ years on the existing SCN site). Even now as I type in this box using Ctrl+V from a simple notepad copy of simple text make the view blink with nothing happening. Same happens for trying to use the hyperlink option here in the editor. The odd thing is that it works fine when switching to the html editor view.
Although my comments are not related to the SCN beta, the behavior with IE and editor views is not new, but perhaps more related to the underlying code and interaction with IE.
