There' s a lot of vibration going on in a bow and screws vibrating loose is something that' s a never ending process. You need to check each screw on your bow and accessories at least once a month.

Maybe if you told us what kind of sight you have, someone can tell you how to adjust the windage on it. Different sights have different ways of adjusting windage. Some sights have pins that move individually and some sights move all the pins at once. It might save you a trip to the shop and it' s something you really do need to know how to do yourself. Pro shops are few and far between when you' re in the woods.
