Just installed Q2 and all my RadWindow implementation are off. Now, all RadWindows are visible by default. this.MyRadWindow.Close() is not doing anything. What do I need to do to fix this?

Hello Tolga,

Probably you have defined your RadWindow controls in the XAML of the main page, hence the problem. We strongly recommend not doing this and from SP1 the control will throw exception if this happens. You could check the following for instructions about the correct declaration of RadWindow:
