If user define maxlength then script Ice.txtAreaMaxLen is fired on some events, like below:

<TEXTAREA onmousedown="this.focus();" onkeydown="Ice.txtAreaMaxLen(this,140);" onblur="iceSubmitPartial(form, this, event);" onchange="Ice.txtAreaMaxLen(this,140);" (...)></TEXTAREA>

But the same script cannot be fired onkeydown and onchange. Event onkeydown should return false if new char exceeds range

This patch should helps

<TEXTAREA onmousedown="this.focus();" onkeydown="return Ice.txtAreaMaxLen(this,140);" onblur="iceSubmitPartial(form, this, event);" onchange="Ice.txtAreaMaxLen(this,140);" (...)></TEXTAREA>

Ice.txtAreaMaxLen = function(field, maxlength) {
    if (maxlength >= 0) {
       if(field.value.length == maxlength)
          return false;
       if(field.value.length > maxlength)
         field.value = field.value.substring(0, maxlength);
    }
   return true;
}
