Showing child form shows 2 forms

[kl4s3k]

To replicate:

1. Create a Windows Forms project (inherit MetroForm)

2. Add another windows form (inherit MetroForm)

3. From the first form, create an instance of the second form with properties:

   TopLevel = false; Parent = this;

4. Show the second form

Result:

The second form is shown, along with another, regular windows form with nothing but a black background and no title.
