When using a RadBusyIndicator on a RadBackStageItem I receive the following error.
Dispatcher Unhandled Exception.
OnCurrentTimeInvalidated
Cannot animate the 'Opacity' property on a 'System.Windows.Controls.ContentPresenter' using a 'System.Windows.Media.Animation.ObjectAnimationUsingKeyFrames'. For details see the inner exception.Line: 0Column: 0
This happens on a dispatcher thread after the background thread has finished and I set the IsBusy to false.
