Im not experiencing any problems with mine but would like to see how you fixed it in the event mine do have issues down the road...I own a glass company in Minnesota and use structural shims for aluminum frames etc. if you notice the u shaped fitting on the back of the latch is meant to bend and hold the latch in place. If you apply 1/16" shims with hot glue or epoxy (to hold shims during install) place them on the open ends of the "U" where they contact the door you can tighten them enough not to rattle and the plastic shim keeps it in place. If people are interested I can take pictures to help you out.
