AbortInternal error

Ved at bruge RedirectToMobilePage metoden får jeg følgende fejlmeddelelse:

[Source:]        mscorlib
        [Method:]        AbortInternal
        [Message:]        Thread was being aborted.
        [StackTrace:]          at System.Threading.Thread.AbortInternal()
  at System.Threading.Thread.Abort(Object stateInfo)
  at System.Web.HttpResponse.End()
  at System.Web.HttpResponse.Redirect(String url, Boolean endResponse)
  at System.Web.Mobile.MobileRedirect.RedirectToUrl(HttpContext context, String url, Boolean endResponse)
  at System.Web.UI.MobileControls.MobilePage.RedirectToMobilePage(String url, Boolean endResponse)
  at System.Web.UI.MobileControls.MobilePage.RedirectToMobilePage(String url)
  at DayPlanUI.btnMoveStart_Click(Object sender, EventArgs e)

Nogen der kan fortælle mig hvad det er der går galt?
