Hi, 

Wehave fixed other issues and will update it soon.

I can't reproduce the paste issue. 

Because browser don't allow script to access the clipboard , so we can't do the paste job directly.

If you don't like the paste button , you can modify the /richtexteditor/scripts/config.js , remove the striked text in line 181
