I have a form in infopath connecting to sharepoint.when I run the form in sharepoint, all textes are in the one line, I can not insert new line in the rich text box in the form.what should I do?
If I recall correctly, in browser forms the behavior of text box and rich text box controls is different from the client -- I don't think they will auto-size. Try making your text controls bigger prior to publishing so that you have room for a couple of lines.
