Using the mouse event handling in mvvm while maintaining default shortcut keys

Dear Gurus!

When I try to use mouse event handlers (mouse click and mouse move handlers) in silverlight application default shortcut keys for zooming operation (Left mouse + Sthif Key + Drag) do not work. How to fix?

I solved the problem by replacing MouseButtonEventHandler on MouseClick event handler. It was so:

myMap.MouseLeftButtonDown += new MouseButtonEventHandler(Map_MouseClick);

and now I did so:

myMap.MouseClick += new EventHandler<Map.MouseEventArgs>(Map_MouseClick);

and all works fine, but it is interesting how to use the first MouseLeftButtonDown event?

myMap.MouseClick += new EventHandler<Map.MouseEventArgs>(Map_MouseLeftButtonDown);
Not Check but this should work

I noticed that on the one-click event handler is called 2 times. What may be the reason and how to fix?

This is the code in the ViewModel:

myMap.MouseClick += new EventHandler<Map.MouseEventArgs>(Map_MouseClick);

 private void Map_MouseClick(object sender, ESRI.ArcGIS.Client.Map.MouseEventArgs e)
{
 }
