Piers,
Yes, that is strange. I think the problem is that, as you said, the
multiwindow mode is assuming that the screen is based at 0, 0. That
isn't a problem for the non-multiwindow mode, but there was obviously
some sort of oversight in the multiwindow mode that caused this problem
to show up. I may look into it eventually, but if you have any
inclination to peek at the source yourself (it is accessible via cvsweb
and well commented) then I would appreciate it if you could try to
locate the problem for me.
