Hi,I'm intermittently experiencing an error when rapidly changing map scales (i.e. from very large to very small, or vice-versa) wherein my application will crash. It appears that the LayerCanvas.ArrangeOverride is, for some reason, attempting to set an invalid Width property on the FrameworkElement's dependency property. Based on this link, it appears that the issue was carried over from the Silverlight API: http://stackoverflow.com/questions/14051823/unhandled-error-in-silverlight-application-code-4004-sys.... Has anyone else encountered this problem and been able to work around it? The following is a snippet of the stack trace with the offending method:System.ArgumentException: '-907.750834278924' is not a valid value for property 'Width'.
