Introjucer became very slow when I changed component's attribute

Hi, everybody. I used Introjucer to build a project ( vs2010 ). I created a child component and there were more than twenty gui components on it, most of them were textEditor.

 The problem is , the Introjucer being blocked long time when I changed some component's attribute. It took me too many time to edit component, such as "text colour", "position", etc.

The Introjucer I used was release version and compiled with VS 2010.


Did someone have the same problem ?
