You can either make the field grow to hold all of the text or you can limit the user to typinng in the viewable area (a check box on the object page). To do th e1st suggestion you have to build the entire form with this in mind. It must be flowed and dynamic.
Is there some type of tutorial in place somewhere that shows me how to do this? I tried building a dynamic form, and it wasn't working there...ARGH!!!!
What if I increase the size of the text entry field vertically? Would that work?
