More and more of my custys have been developing some every strange behavior, presumably due to the unseasonably warm temperatures we have had this winter. Many of them have started leaving their upstairs windows ever so slightly open and locked in this position via the handle from the inside. I know not all window handle frames combs allow this to be done, but clearly quite a few of the older upcv and ali ones do. Anyway I wont use WFP on these because I'm worried about water getting inside, and its no point climbing up the ladder to close them becuase you can only close by opening the handle from the inside. have any of you experienced this if so how do you deal with it? I thinking of putting some anonymous posts on FB saying "beware burglars broke in thru my window even though it only a little bit open and locked with handle from the inside"
