It is also worth checking that the rubber seal fitted to the header rail is still properly located. They can come unstuck at the corner, making it a "challenge" to locate the rail properly.
This was a problem on my old hood, despite attempts to re-glue it into place. I used to put a wooden clothes peg into the slot on each side when the hood was stowed. Worked a treat.
