Hi,

I just tried the following:

Code:
{
    xtype: 'container',
    layout: 'vbox',
    scrollable: 'vertical',
    items: [
        {
            xtype: 'container',
            html: 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. Fusce posuere, magna sed pulvinar ultricies, purus lectus malesuada libero, sit amet commodo magna eros quis urna.'
        }
    ]
}
Running it inside Chorme, Safari, Android, iOS works fine, but in IE10 it won't keep 100% in width. I runs out of the screen.
If I remove the layout: 'vbox' it works fine.

Any idea what I am doing wrong?
