And also, it doesn't stetch a lot :
<math>
<mover accent="true">
<mrow>
<msub><mi>A</mi><mn>1</mn></msub><msub><mi>A</mi><mn>2</mn></msub></mrow
>
<mo>&frown;</mo>
</mover>
</math>

and

<math>
<mover>
<mrow>
<msub><mi>A</mi><mn>1</mn></msub><msub><mi>A</mi><mn>2</mn></msub></mrow
>
<mo>&frown;</mo>
</mover>
</math>

do render differently under Mozilla (at the moment, i cannot test it 
under mathplayer) : the accent is stretched a little, but not enough !

And if the width of the base is getting larger, the accent does not 
stretch anymore !
