I have seen that continuous headers can be problematic due to lateral forces. However, in my situation the "header" is actually a 4x6 purlin which is above the top plate.
The original purpose of the purlin is to support the oversized overhang on the left (2'). But after putting it into the design I realized it was redundant to have a 4x6 above the windows followed by a 2x6 header above each window, so I removed the individual headers above each window. Is having a continuous header like this problematic in this case?
