FixedToolWindow appears as floating bar when ShowInTaskbar is false - how can I stop this?

Question

I'm using a WinForm configured as a FixedToolWindow. I've set ShowInTaskbar to be False - I'm using a NotifyIcon to manage restoring the window, once it's been minimized.

When I minimize the window, it becomes a bar in the bottom left corner of the primary screen - a window title bar, I'm guessing. I can move it and if I then restore the window and re-minimize it, it returns to the new position. If I set ShowInTaskbar to True, it disappears on minimize.

How can I stop it from appearing as this bar when ShowInTaskbar is False? When minimized, I want the NotifyIcon to be the only visible artefact of its existence.

Try using the Form.Hide() and Form.Show() methods instead of minimizing/restoring the WindowState and leave the ShowInTaskBar property to true.
