Once the object has been identified, the ExecuteEvent function is called. This function changes the cursor shape (object dependent) to an "arrow", a "cross", a "hand", etc. The crosshair is not implemented. This could be implemented as an option. As you say, the option "EventStatus" indicates very precisely the axis coordinates corresponding to the cursor position on an object. Rene Brun
