This is a browser limitation and can't easily be solved in Ext.

The left section will only do mouse wheel scroll if it is set to overflow:auto, but that would mean it would show a scrollbar on the right side of the locked section.

hi,I also saw this bug,and that it was not in Ext 4.* ,so i saw the source code of Ext 4.but it looks complicated,so ,can you show me ieda or suggestion to solve this bug above ext 3.3


the code in Ext 4:


view = me.getView();
view.on({
afterrender: function () {

view.el.scroll = Ext.Function.bind(me.elScroll, me);


me.mon(view.el, {
mousewheel: me.onMouseWheel,
scope: me
});
},
single: true
