This behavior is by design.

 

When the editor page loads, Cute Editor will not steal your page focus.

if you want the editor takes the focus when the editor page loads, please set the Editor.Focus Property to true.

Editor.Focus Property

Specifies whether the editor grabs focus when the page loads. If this property is set to true then the editor will take focus, if it is set to false it will not.

 

However if you open a editor popups, the CuteEditor will think you are working with the content. So when you close the popups, the editor will automatically take focus.

 

Hope it helps.

 

If it doesn't make sense to you, please let me know.
