In a specific customer's application, we have added two steps -

- Wait for Exists 'BtnReportsButton' 

- Click BtnReportsButton

In IE 10 both steps pass successfully. In Chrome 32 the first wait step passes, but the click step fails with the following exception: 

System.NullReferenceException: Object reference not set to an instance of an object.   at ArtOfTest.WebAii.Core.Browser.ContainsPoint(Point point)   at ArtOfTest.WebAii.Silverlight.SilverlightApp.ValidateMouseLocation(Point point)   at ArtOfTest.WebAii.Silverlight.UserInteraction.Click(MouseClickType clickType, Point offsetPoint, OffsetReference reference)   at ArtOfTest.WebAii.Silverlight.UserInteraction.Click(MouseClickType clickType, Int32 x, Int32 y, OffsetReference reference, ActionPointUnitType unitType)   at ArtOfTest.WebAii.Design.IntrinsicTranslators.Silverlight.Descriptors.ButtonActionDescriptor.Execute(IApplication hostApp)   at ArtOfTest.WebAii.Design.Extensibility.XamlActionDescriptor.Execute(IAutomationHost autoHost)   at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.ExecuteStep(Int32 order)

Steps to reproduce and a sample test project are attached in the internal description.
