Normally my code doesn't care when or how often willDisplayCell: is called and
is in fact called more often than in a normal table view as my code highlights
the cell that the mouse is over.
The odd thing is on this occasion the background which I draw for the
highlighted cell actually draws over everything else rather than going behind
it.
Obviously as this happens normally due to the tooltip, I will have to
investigate as to why the problem occurs and possibly consider where I do the
drawing.
Thanks for your help,
Josh

It probably gets called to draw the tooltip expansion cell. If there is a bug
here, it's that willDisplayCell: doesn't get called after the window is
reopened.
You need to fix your code so that it doesn't care when or how often
willDisplayCell: is called. You should not be doing much if any meaningful work
in this method.
