wx2.8.4-mac default position in a scroll window bug?

[Matt Connolly]

I have created a document frame with a scroll window, and a custom  
subwindow (inherits from wxWindow) inside that.

I notice that if the subWindow is positioned at wxPoint(0,0) then  
scrolling works as expected.

If the subwindow is positioned at wxDefaultPosition, then scrolling  
doesn't work perfectly.

What happens is that if you scroll into the document, and then back  
to the beginning, the document has actually over scrolled and you  
cannot see the left edge (I'm scrolling horizontally to represent a  
time axis). The part of my subwindow representing time=0 (at the  
left) cannot be seen, it's gone off the edge of the main window, even  
though the scrollbar is at its leftmost position (position = 0).


Anyway, I have my app doing what I expect now by using position =  
wxPoint(0,0) at initialisation instead of wxDefaultPosition.

Has anyone else seen this?
