I had a similar problem with a grid panel in IE, where on a refresh the grid would scroll to the start of the grid. The solution was to add the following function to the grid panel:

    fixIeScrollPosition: function() {
        console.log("fix ie scroll position ");
        var scrollTarget = this.getScrollTarget();

        var currentScrollPosition = scrollTarget.getEl().getScroll().top;
        var expectedScrollPosition = scrollTarget.bufferedRenderer.scrollTop;

        var correction = expectedScrollPosition - currentScrollPosition; // will be 0 in non-IE

        scrollTarget.scrollBy(0,correction);

    },

This is triggered by refresh events.
