I now notice that Cesar wraps the entire ".Navigate(lcHTMLfile)" routine in a TRY/CATCH and then displays a "cannot load file" message to the user. Which probably explains why the error message is not so common. But it would be helpful to know why the navigate fails (antivirus, file copy timeout, navigate timeout, ...).
