text editor in smartform

Hi,

The text editor in smartform is not coming, instead I am getting the text "Use the full screen text editor", which is followed by the text editor icon. clicking this icon takes me to the standard text editor. In the standard editor I am not able to select my paragraph and character formats, also it does't allow me to drag and drop fields.

How can I get the subscreen text editor enabled in smartform?

Regards,

Vijai
