Where are you pasting it? In the header, body, footer, or ?
When you enter browse mode, what view option have you selected, View as Form, View as List or Table View?
In the header, although I can't seem to resize the header to make enough room for it.
View option is Form only.
Try holding down the Alt key (windows) while dragging the boundary line down to make the header larger. There's a Mac equivalent, but I don't recall it off hand.
If you are using form view, you don't actually need the header, you can move any object currently in the header down into the body, click the header label and press the delete key to delete it. Then you can design your layout solely in the body layout part. The result looks and functions the same in Browse Mode as long as you do not specifie either of the other view options.
