Owner form closes unexpectedly

I have several forms who have their ownership set to another form. They can be launched through buttons on the owner form. However, if I have more than one open, when I close the first one created, the owner form closes to. This does not happen if only one form is open, but once I open up multiple, and close the original, the owner form also closes. What is causing this? Can this be fixed?

Sorry. Crystal ball's a little fuzzy tonight!

A form that is owned by another will close when its owner is closed. You probably confused who owns who somewhere.
