I am currently using the ArcGIS WPF API v2.2. I have created a custom map tip and set the GraphicsLayer.SetMapTipHideDelay property. When I add some graphics to the map the maptip display and stays on the screen for the specified time. When I first Draw a polygon on the screen then throw some graphic points on top of the polygon and then try and access the maptip. They stay on the screen only when the mouse is moved over the point. The delay is being ignored. Is this a bug? Thanks.
