Hi,

More informations about this problem. It seems the btn refers to a div 
element ! In the HTML source I get :
<div id="OpenLayers_Control_MouseToolbar_pan" style="position: absolute; left: 
5px; top: 308px; width: 28px; height: 28px;" title="Drag the map.">
<img id="OpenLayers_Control_MouseToolbar_pan_innerImage" style="position: 
relative; width: 28px; height: 28px;" src="js/img/panning-hand-on.png"/>
</div

The img tag got no alt and title parameters. So the text we can see in IE come 
from the div elements.

Y.
