before opening a form it first checks to see if it's already opened and if it is, it brings the current form forward, if it's not then a new instance is made and it's showed

Check the WindowState property of the form. If it is equal to FormWindowState.Minimized then either set it to FormWindowState.Normal (to Restore it) or FormWindowState.Maximized (to maximize the form).
