First of all thanks for this good and useful plugin!
I noticed that in the IExplorer 9 some colorpickers are not shown. For example in the setup for the shortcode Box. Also if you click on insert shortcode nothing happens. With Mozilla Firefox this problem does not occure and everything works fine.
Another thing I would like to mention is that I was using the shortcode Border. After update to the last version of this pluging they were broken and I had to replace them with the shortcode Box. At the end I decided to use the Divider.
So if you update and you was using a lot of the shortcode Border be prepared. You have to change them, there is no automatic conversion.
Nevertheless it is a useful and good working plugin.
