Assuming that the exposures were all at speeds > 1/60 sec, James, I can only
suggest that, logically, you must have an uneven timing problem with the
first shutter curtain, which is being "caught up" by the second curtain for
an instant, causing the exposure slit to close, before resuming its
trajectory (on the XP2, vice versa on the Provia). That would explain why
exposures at speeds < 1/60 sec were OK - the second curtain doesn't start
until the first has already reached destination.
Whether that is mechanically possible (let alone likely) is, I regret, an
entirely different question - and beyond me. But I doubt that it will be
difficult to put right.

Subject: [OM] om4ti problem?
got 7 rolls of film back from my holiday in china and noticed somthing a
little strange about a few of the shoots.
On one shot using ilford xp2 @ 100 asa there is a thin *white* line about
2.3rds of the way along the negative (landscape) and almost with width of
the negative running vertically but not quie reaching either edge.
On a few of the provia 100F shoots there is a simular thin line possibly in
around the same place but the thin line is *white* too the length of the
thin line seems to vary from slie to slide
any ideas? I thought light leak but
1. then xp2 shoot should have a black line not white since its a negative 2.
when I had light leaks before they where around the edges of the film and
where greenish 3. its very occasional maybe one per two rolls and the long
shoots 2+ minutes where fine
