How to get rid of clutter during the transition?

Question

WPF

From the AgentsNew window, when the button is pressed, the following code is executed:

ManagerAgents taskWindow = new ManagerAgents();
taskWindow.Hide();
taskWindow.Show();

There is a heaping up of the same window on the same one already open.
