    This is the skeleton of a template we have to use. In Firefox and IE it's not causing any problems. But there is major slowdown when it's in Chrome. Outside of the editor as it's own html file it has no problems. Just when it's in the Telerik Editor

    As it was only suggested as a "possible" workaround can we get a little more information on why this is happening and if it's a bug that will be fixed in the future? Obviously the resize widget function was put in your code for a reason and using a workaround isn't really a solution in the long run.

    Hello Chad,

    This issue happens dye to the feature provided in the RadEditor and allows users to resize images and tables in the content area. The feature is designed to initialize a complex logic of resizable div elements in the content that upon event handlers attached to the resize handles DOM resize event triggers a logic to change dynamically the size of the selected table or image element.

    Due to its complexity, when multitude of tables are nested, the initialization process causes a performance issue and it appears that there are scenarios where Chrome cannot handle to render the elements and freezes.

    This matter is logged and will be further investigated by the dev team, although due to its complex matter I am unable to provide a firm estimation when exactly it is going to be properly resolved.

    Do not hesitate contacting me again in case you need further information on this matter.

    Regards,
