For one of the modules in my project, I am utilizing a rad editor to edit HTML. Everything functions perfectly across all browsers except for IE10 and IE9. When using Internet Explorer, inserting a table object from the rad control is not possible. Additionally, features such as adding symbols and undoing actions do not work properly. If any of these menu options are clicked on, the editor in design mode becomes uneditable. To resolve this issue, switching between HTML mode and design mode is necessary. Furthermore, there is noticeable shaking in the UI on the right side and bottom of the editor.
Any assistance would be greatly appreciated!
