Windscreen Loose seal on front pillar

[camshaft]

Don't know if this has already been discussed but I couldn't see it anywhere.

Three or four times now, the rubber seal between the windscreen and the passenger side pillar has come loose while driving. It's still attached at the top and bottom but the middle of it comes out and flaps against the trim making a hell of a noise and making some marks on the plastic trim. When I stop driving and go and look at it, it has replaced itself in the right position and seems really secure.

It only seems to happen at motorway speeds, on days when there is a cross-wind. It's going in for it's first service next week so I'll mention it then and hope to get it replaced but was just wondering if this had happened to anyone else.
