>>As I mentionned several weeks ago, the aspect ratio preservation mechanism functions very poorly in i.e.. For one, the
vertical component is ignored. Is there no way to make this work in IE?

This problem is caused by IE. Right now Editor.MaintainAspectRatioWhenDraggingImage property is best solution we have.

In the version 5.2, we introduced a new property.

Editor.EnableObjectResizing Property

Specify whether or not to allow the users resize an object winthin the Cute Editor. For example, if you want to prevent people from resizing images, table winthin the Cute Editor, you can set it to false.

Hope it helps.

Let me know if you have any further questions.
