Vertical Scroll on DIV

[jmir]

Hi,

I'm trying to insert a scrollable DIV on a plan. Inside it, there is a table which can vertically overflow (depending on the number of lines in the table).
In older firmwares I'm using this code and it's working:

Code:

var quadre = $("<div id='requadre'></div>").css({
      position: 'relative',
      width: 1800, height: 800,
      top: 70,  left: 100,
      border: '1px solid white',
      overflow: 'auto',
      background: 'black',
  }).appendTo('#plan-59');

In newer firmwares, the scroll bar appers but it seems disabled...

Any idea about what can be happening?
Thanks
