TreeView TreeNode LabelEdit accepts only one character C++ VS2005

The following MDI Form only allows me to type one character in the
TreeNode's edit control unless the child window is focused in a Normal
(or Maximized) WindowState.

After entering one character the child form is appears to receive
focus, ending the edit operation. If there is more than one MDI child,
then the first child receives focus and is brought to front.

How can I fix this?

public ref class Form1 : public System::Windows::Forms::Form
{
public:
Form1(void)
{
InitializeComponent();
}
protected:
~Form1()
{
if (components)
{
delete components;
}
}
private: System::Windows::Forms::TreeView^ treeView1;
private: System::ComponentModel::Container ^components;

#pragma region Windows Form Designer generated code
/// <summary>

void InitializeComponent(void)
{
this->treeView1 = (gcnew
System::Windows::Forms::TreeView());
this->SuspendLayout();
//
// treeView1
//
this->treeView1->Dock =
System::Windows::Forms::DockStyle::Left;
this->treeView1->LabelEdit = true;
this->treeView1->Location = System::Drawing::Point(0, 0);
this->treeView1->Name = L"treeView1";
this->treeView1->Size = System::Drawing::Size(200, 471);
this->treeView1->TabIndex = 0;
//

//
this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
this->AutoScaleMode =
System::Windows::Forms::AutoScaleMode::Font;
this->ClientSize = System::Drawing::Size(696, 471);
this->Controls->Add(this->treeView1);
this->IsMdiContainer = true;
this->Name = L"Form1";
this->Text = L"Form1";
this->Load += gcnew System::EventHandler(this,
&Form1::Form1_Load);
this->ResumeLayout(false);

}
#pragma endregion

private:
System::Void Form1_Load(System::Object^ sender,
System::EventArgs^ e)
{
Form^ f = gcnew Form();
f->MdiParent = this;
f->Show();
f->WindowState = FormWindowState::Minimized;

TreeNode^ tn = this->treeView1->Nodes->Add("Top1");
tn->Nodes->Add("sub1");
tn->Nodes->Add("sub2");
tn = this->treeView1->Nodes->Add("Top2");
tn->Nodes->Add("sub3");
tn->Nodes->Add("sub4");
tn->Nodes->Add("sub5");
tn = this->treeView1->Nodes->Add("Top3");
tn->Nodes->Add("sub6");

this->treeView1->ExpandAll();
}
};
 
The solution is to put the TreeView inside a Panel (or possibly some
other container control) instead of directly into the Form.
