I keep getting a "A first chance exception of type 'System.NullReferenceException' occurred in Mogre.dll" and i debugged it to this code sniped in example application.

haven't look any further in to it. is it some common thing when we just ignore it?



// update stats when necessary

            try

            {

                OverlayElement guiAvg = OverlayManager.Singleton.GetOverlayElement("Core/AverageFps");

                OverlayElement guiCurr = OverlayManager.Singleton.GetOverlayElement("Core/CurrFps");

                OverlayElement guiBest = OverlayManager.Singleton.GetOverlayElement("Core/BestFps");

                OverlayElement guiWorst = OverlayManager.Singleton.GetOverlayElement("Core/WorstFps");



                RenderTarget.FrameStats stats = window.GetStatistics();



                guiAvg.Caption = avgFps + stats.AvgFPS;

                guiCurr.Caption = currFps + stats.LastFPS;

                guiBest.Caption = bestFps + stats.BestFPS + " " + stats.BestFrameTime + " ms";

                guiWorst.Caption = worstFps + stats.WorstFPS + " " + stats.WorstFrameTime + " ms";



                OverlayElement guiTris = OverlayManager.Singleton.GetOverlayElement("Core/NumTris");

                guiTris.Caption = tris + stats.TriangleCount;



                OverlayElement guiDbg = OverlayManager.Singleton.GetOverlayElement("Core/DebugText");

                guiDbg.Caption = mDebugText;

            }

            catch

            {

                // ignore

            }
