When the active OS theme is Windows 7 Basic, the Ribbon displays blank when restoring a minimized window programmatically.

Here is the code snippet. Form2 is just another form with UltraToolbarsManager.

public partial class Form1 : Form
{
Form2 frm = new Form2();

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
Infragistics.Win.AppStyling.StyleManager.Load(Application.StartupPath + @"..\..\..\Office2007Black.isl");
this.appStylistRuntime1.LoadFromStyleManager();
}

private void ultraToolbarsManager1_ToolClick(object sender, Infragistics.Win.UltraWinToolbars.ToolClickEventArgs e)
{
switch(e.Tool.Key)
{
case "ButtonTool1":
if (frm == null || frm.IsDisposed)
frm = new Form2();

frm.Show();
break;
default:
frm.WindowState = FormWindowState.Normal;
break;

}
}
}

Aside from changing the OS theme to Classic or Aero, is there some other workaround?
