Navision (3.01 B) crashes on OnFormat

Hi how can you crash Navision (3.01 B) everytime? Quite simple![8D] Create a form with one control (textbox), rename this control, go to the OnFormat - trigger of this control, write: CurrForm.YourControlName.Update; Save this form AND ALL OTHER UNSAVED OBJECTS. Try to run this form. If you are annoyed about your company, put this code into the main menu [}:)]. bye André
