Ok, so i've had my window in for about 6 months, and everythings been going fine.....except for the locking strip. It's been about 1/4 out of place for a few months now, and just recently came about 1/2 to 2/3 done, so i just pulled it out (as it started going further once i messed with it). At this point, is the locking strip really necessary, and what is the worst thing that could really happen to my window?
