My way is to set the unused forms as hidden by Form.Hide().
ex. Set Form2 as active form
Form2.Show()
Form1.Hide()
and switch back to Form1
Form1.Show()
Form2.Hide()
This can solve your first problem...
However, you better watch out when you switch between forms,
Form.Activated event will be triggered.
