I moved up to wxPython 2.6 (and Python 2.4), using PythonCard from CVS 
(from yesterday).

I saw 2 (or 3) differences (small sample files below).

1. (as originally reported by Brad)
I have a checkbox which overlaps a (later in the rsrc file) staticText.
In wxPython 2.5.3, this "works", in 2.6 it doesn't.

I think 2.6 is correct - the staticText should be drawn after the 
checkbox's label, and so it should hide the checkbox's text, and so I 
believe 2.6 is correct.
So this is a compatibility warning, but not a bug in wxPython 2.6 (nor 
in PythonCard).

2. transparent PNG image.
I have an imageButton where the image is a file reference to a PNG file 
with transparent pixels. The imageButton has border set to 
"transparent". (Needs to be "transparent" to see the problem, works OK 
if the button is style "3d").

In wxPython 2.5 this works properly. In 2.6, the background of the 
button shows what was there before the window opened. i.e. it's as 
though it were transparent all the way through the background of the app 
window.

3. missing PNG image
if the image file is missing, both versions report "cannot load image 
file". In 2.5, it works OK - so the effect is simply that where the 
button is shows as background. In 2.6, it works as though the entire 
image were transparent - i.e. you can see  the desktop behind the app 
window. (so far, just the same as problem 2).

BUT - the transparent area is far larger than the imageButton's size. 
The imageButton has size 20,20 but the transparent area is something 
like 100,20. So this might be another bug, or it might not.

So I think 2 and 3 (if 3 is actually different, not just a manifestation 
of 2) are wxPython 2.6 bugs, not things that need to be, or even can be, 
changed in PythonCard.

but note that as it says in problem 3 above, if this file is missing you
