This seems likely to be pilot error since it seems
it would have been noticed by now if it was wxPython
problem, but I'm not seeing it...
I create a grid with more rows than can be shown and
it displays as expected with vertical scrollbars and
displaying cell (0,0) in the top left corner.
But if I call the Grid method MakeCellVisible(0,0)(which
I presume should have no effect since the cell is already
visible), the grid is scrolled down so that only the bottom
border of the top row is visible.
Conditionalizing the call using .IsVisible(0,0) doesn't
help because it seems to return false, even though the
cell *is* visible. Nor is problem limited to row 0, it
occurs with any row number.
As I said, I strongly suspect I am doing something wrong
and would appreciate a clue. Demo code attached.

When the Frame.__init__ is called then the frame still hasn't been shown, so it hasn't been sized yet, and so there has been no size event to cause the layout of the sizer, and so the grid can still be considered as having an undefined size. (Actually it's probably 20x20.) So at the time you call MakeVisible it is doing it's best to do what you ask, but thinks it only has a very small number of pixels to do it in.
