For an individual existing Mtext object, select it and look at its Properties -- its Width is probably zero [which doesn't actually mean zero, but means "no defined width" -- there's no numerical character or symbol to represent infinity]. Change that to something reasonable under the circumstances, and you'll get grips you can drag to set a width that it will wrap within.
For making new Mtext with the Mtext command, does it not prompt you for an opposite corner, with an option for specifying a Width numerically? Or are you talking about Mtext made in a Leader command? In my older version here, though Help says it's supposed to ask for a width, it doesn't, and I get zero width [I hope they've fixed that in newer versions]. So I usually make Mtext separately so I get word wrapping, and draw Leaders with no annotation.
If existing Mtext with zero width is made by some routine, check how it's doing it. If with (command), is it specifying zero width? If with (entmake), is it including a 41-code width entry [for zero width, it would presumably be be '(41 . 0.0) or '(41 . 0) or (cons 41 0.0) or (cons 41 0), or possibly (cons 41 somevariablename) if that variable name holds a value of zero]?

If something I wrote can be interpreted two ways, and one of the ways makes you sad or angry, I meant the other one.
