Before opening a new tab, get a reference to the UltraTabbedMdiManager's ActiveTab, and after the new tab is added, call Activate() on the original ActiveTab.  For example:

            MdiTab activeTab = this.ultraTabbedMdiManager1.ActiveTab;

            Form1 f2 = new Form1();
            f2.MdiParent = this;
            f2.Show();

            activeTab.Activate();
