The Mac version of wxPython 2.5.2.3 is dramatically improved over 
previous releases, but it still has some z-order issues and doesn't 
really support overlapping widgets like you can do on Windows.

If you are using a background image set via the Background Info... 
dialog instead of an actual component like Image, ImageButton, or 
BitmapCanvas, then that is different since the background image is just 
drawn on the panel and not actually an overlapping control. Using a 
background image seems to work reasonably well on the Mac with the 
upcoming wxPython release except that text fields will leave behind a 
white rectangle when the field loses focus and it will probably require 
an extra Refresh() and Update() call on the underlying panel to get 
that to be cleaned up.
