Yeah, if you reach 75nm and it hasn't turned you, then you might be looking at a problem. I would check your flight plan that you filed to be sure it's in order (check distances as I've found some points can have the same ID in a different country). Also a good thing to do is be sure you add all the points in your procedure to the FMS when you come in. If you add the PROC points to your FMS based on your approach type, it might also help you determine what the ATC is doing. Even the built-in ATC won't forget about you so at some point it IS going to turn you. Trust the ATC. :-P
