Hello again, thanks for the kind support, but unfortunately there is still an occasional error that occurs the next time the application gets launched after settings got modified in the previous session (e.g. changing GUI language). The screenshot I attached shows the plain .NET error message; a click on the "Details" button brings up the following additional information: ************** Ausnahmetext ************** System.Runtime.InteropServices.COMException (0x80210006): Ausnahme von HRESULT: 0x80210006 bei WIA.PropertyClass.set_Value(Object& pvResult) bei iCopy.Scanner.set_Resolution(Int16 value) bei iCopy.Scanner.get_AvailableResolutions() bei iCopy.frmImageSettings..ctor() bei iCopy.mainFrm.LoadSettings() bei iCopy.mainFrm.mainFrm_Load(Object sender, EventArgs e) bei System.Windows.Forms.Form.OnLoad(EventArgs e) bei System.Windows.Forms.Form.OnCreateControl() bei System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) bei System.Windows.Forms.Control.CreateControl() bei System.Windows.Forms.Control.WmShowWindow(Message& m) bei System.Windows.Forms.Control.WndProc(Message& m) bei System.Windows.Forms.ScrollableControl.WndProc(Message& m) bei System.Windows.Forms.ContainerControl.WndProc(Message& m) bei System.Windows.Forms.Form.WmShowWindow(Message& m) bei System.Windows.Forms.Form.WndProc(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) ************** Geladene Assemblys ************** mscorlib Assembly-Version: 2.0.0.0.

What makes this problem a bit tricky is the fact that iCopy will start up correctly about one time in ten times even with the correct settings (now, I also get the German GUI texts presented again). But I'm sure to have a perfectly working copy of iCopy at my fingertips soon thanks to your great efforts for this freeware tool. So thanks again for keeping me updated that fast ! Sincerely yours Andreas Hüller
