Hi,

I was playing around with the column layout from the site's Demo page and one thing I observed with my
code below is that after resizing Firefox's width smaller or larger, the column doesn't dynamically re-adjust.

Something wrong with my code?

Code:
var searchPanel = new Ext.FormPanel({
        labelAlign: 'top',
        frame: true,
        region: 'north',
        border: false,
        bodyStyle:'padding:5px 5px 0',
        //width: 1024,
        height: 100,
        //layout: 'fit',
        items: [{
            layout:'column',
            items:[{
                columnWidth:.25,
                layout: 'form',
                items: [{
                    xtype:'textfield',
                    fieldLabel: 'Type',
                    name: 'type'
                }]
            }, {
                columnWidth:.25,
                layout: 'form',
                items: [{
                    xtype:'textfield',
                    fieldLabel: 'Cylinder(s)',
                    name: 'cyl'
                }]
            }, {
                columnWidth:.25,
                layout: 'form',
                items: [{
                    xtype:'textfield',
                    fieldLabel: 'Make',
                    name: 'make'
                }]
            }, {
                columnWidth:.25,
                layout: 'form',
                items: [{
                    xtype:'textfield',
                    fieldLabel: 'Model',
                    name: 'model'
                }]
            }]
        }],

        buttons: [{
            text: 'Search'
        }]
    });

Ext.onReady(function(){

        Ext.QuickTips.init();
        //Ext.state.Manager.setProvider(new Ext.state.CookieProvider());

        var viewport = new Ext.Viewport({
            layout: 'border',
            frame: false,
            border: false,
            items:[
                new Ext.BoxComponent({ // raw
                    region:'north',
                    el: 'pageHeader',
                    height: 135
                }), {
                    region: 'center',
                    layout: 'border',
                    id: 'innerBorderId',
                    frame: false,
                    border: false,
                    items:[
                          searchPanel  
                    ]


                }]
        });

    });
thanks!
