problem with TreeView and Form.ShowInTaskbar attribute

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I've run across something strange:

When the Form.ShowInTaskbar is changed TreeView controls on that form
collapse their selected node.

Is this by design, or is it a bug?

I've seen this with VS2003 or windows XP sp2.

To Reproduce this behavior:

1. Create Windows application.
2. put on the form a tree view & a button.
3. add a root node & some child nodes.
4. put this code is the buttons event handler:

private void button1_Click(object sender, System.EventArgs e) {
this.ShowInTaskbar=!this.ShowInTaskbar;
}

5. now expand the tree nodes and press the button.
the selected node of the tree is collapsed!
