Hi,

If you have multiple editors on the same page, there is a severe freezing issue occurring in IE 11 with compatibility mode off.

It is very difficult to recover from and you have to kill the web page windows or log off windows if you were in debug mode in .NET.

I can reproduce this on the demo page, and after much trial and error got it down to these steps.

  With browser IE 11; compat view is off
Navigate to:
http://cutesoft.net/example/Multiple.aspx
(or any page that has two cutesoft editors on it)
Open Notepad side by side (or any other application)

Click inside FIRST cutesoft editor so that the cursor is blinking in the box
Click out of the HTML page to the other application (such as Notepad)
In the still open web page, click inside SECOND cutesoft editor so that the cursor is now blinking in the second box.
The entire webpage is now frozen.  If you were debugging locally, your whole computer comes to a stop and you have to log off.  Task manager won't even kill the window.

Issue is reproducible in IE11 with compatibility view off.
Issue is NOT reproducible in Chrome, or IE11 with compatibility view on.
