I remove the icon and I reinstall Mono ( using this method : http://monofrance.tuxfamily.org/modules/newbb/viewtopic.php?topic_id=132&forum=6) But I got this : Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for System.Windows.Forms.Control ---> System.EntryPointNotFoundException: RegisterWindowMessage at (wrapper managed-to-native) System.Windows.Forms.SafeNativeMethods:RegisterWindowMessage (string) at System.Windows.Forms.Control..cctor () [0x00000] --- End of inner exception stack trace --- at System.Windows.Forms.Application.SetCompatibleTextRenderingDefault (Boolean defaultValue) [0x00000] at CalculPoint.Program.Main () [0x00000] Any Idea ?
