If you want to tighten the roof and stop the wind noise, use electrical heat shrink wrap on the hooks, just put one layer on at a time and use a hair dryer to shrink it, do this a few times, I did mine about a year ago and its still tight, I need to pull the roof then clip it, its that tight...
Saves you from buying and installing new latches, the heat shrink wrap will cost only a few dollars.
anyway, i have a similar problem, i was driving but i forgot to hook the roof back on aftah i parked the car.. so when i was leaving, i didn't realise and was going about 60 kms.. the roof came up, scared the shit outa me.. slammed the breaks n the roof came back down, and now when i was to put the roof back up, i have to hold it down then clip, otherwise it sits about 1cm like kruzzn said.
that could've caused it for me, or another time my mate wanted to put it down but i wanted to keep it up, he unhooked both sides, i hooked my back up, he pressed the button for roof to lower, and a loud crack sound happened, i duno which caused the problem thou.
