Hi ludwig,

I still can not reproduce this isssue. I have tried on win7 IE10.0.9200.16521 and win 8 IE10.0.9200.16384. works on both of them.

Below are my test steps.

1. Link to http://www.richtexteditor.com/demo/.

2. switch to html view and paste the code below to the bottom.

<div>

    <div style="float:left">left</div>

    <div style="float:right">right</div>

    <div>content</div>

</div>  

3. Back to normal view and focus in the left div and user the insert document dialog to insert a file. I also tried to insert a file in the right div.

Please correct me if my steps are worng or need special steps.

Regards,

Ken
