Removing selective formating when pasting using Ctrl+V

Hi

I want to restrict any formating related to colour and font size. Although I have disable those control in FCK editor, but when I am using 'Ctrl+V' I am able to paste text with all those formating.

Is there any way to disable formating when pasting using 'Ctrl+V' or how to rermove the formating tags from the html output.

Thanks & Regards,
Suchi
