Mine have and it does not seem to have been a problem. Here’s a link to the pic I posted and some stats for my second harvest. Flow Hive Statistics
Mine is a Flow Hive Light with three Flow frames in the middle and a couple of normal Langstroths on either side. The problem I have is I need to put starter strip frames on the side ith the window if I want to observe the side of the Flow frame. Lately my girls have been bulging the edges of the flow frame into this space.
