Hi,
This kind of crash happened when map was clicked multiple times and application was switched to view where map was not visible:
System.InvalidOperationException: This Visual is not connected to a PresentationSource.
at System.Windows.Media.Visual.PointToScreen(Point point)
at ThinkGeo.UI.Wpf.MapViewBase.F0U=(Object sender ManipulationCompletedEventArgs e)
at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler Object target)
at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target RoutedEventArgs routedEventArgs)
at System.Windows.EventRoute.InvokeHandlersImpl(Object source RoutedEventArgs args Boolean reRaised)
Maybe exception handling (or some checks if that PointToScreen API can be used) would be good to add to MapViewBase to avoid crash in this kind of case ?
Br, Simo
