richtextbox control

[sivasankari]

hai,
i have created a richtextbox control for my application with help of javascript which works good for windows whereas for Mac machines it is not working so i have done it with a ordinary text area itself. Now the problem is, i need to create a similar richtextbox control that support Mac machines too and inclusively there should be a spell checker incorporated. If anyone knows kindly let me know.

Thanks
