I am not sure whether this should be classed as a bug or not.
When using the VisualStudio2013 Dark Theme and closing a RadWindow it "Shrinks" and fades away. However the window is still active whilst it is shrinking.
In my use case I have a RadWindow as a popup with a RadListBox containing several items. On the RadListBox's SelectionChanged Event some work is carried out and I call Close() on the RadWindow. This happens very quickly and if a user double clicks a RadListBoxItem rather than single clicking the RadWindow it is already closing and the RadListBoxItem below the selected item moves under the curser as the RadWindow "Shrinks". This item then fires the same event.
As a work around I am going to set IsEnabled=false on all my RadWindows before calling Close() as this fixes the issue.
I just wondered whether this could effect other peoples projects in different ways, and whether the IsEnabled=false should be set somewhere else within the Telerik code as an automated process.
