need help on 'restore down' button in Winforms.

What mechanism do I have to provide or what event do I have to handle for the "Restore Down" button to work on the Windows form

Minimize works as expected. When I click on that button, the form minimizes to the app's icon in the taskbar. Clicking on that icon restores the form to the full size.

When I click on "Restore Down" the window closes as it does in Minimize but now I have to perform a right button click on the icon in the tray at bottom and select 'Maximize" to bring it back to full size.

I want to be able to "Restore Down" to a size that does not fill the whole screen and be able to move the app over to my other monitor in a dual monitor environment.

Thank you,

-Greg
