I put this code

IF llStartApp
  DECLARE INTEGER GetLastError IN kernel32
  DECLARE INTEGER CloseHandle  IN kernel32 INTEGER hObject
  DECLARE INTEGER CreateMutex  IN kernel32 INTEGER lpMutexAttributes, INTEGER lInitialOwner, STRING lpName
  IF VARTYPE(oAppObj.oMutex.NAME) = "C"
    MESSAGEBOX('Starting')
    DO set_time WITH prefs.set_time, prefs.nosay_time
    DO SomeManager_menu.mpr
   ** put a bunch of messageboxes here as well
  ...

The application is started OK, but I see 0 messageboxes. Which probably means this code is never executed and I need to find out where exactly the startup code of the application is.

UPDATE. I think I know where the problem also may lie. I call in the command window do Something with param. I think it's calling the exe rather than main program.
