[Bf-committers] Images in Panels..

[Peter K.H. Gragert]

Hallo
My experience in pictures:
http://www.petergragert.info/pmwiki/uploads/Kilon/bgl_error_2.jpg
This looks ok
but here
http://www.petergragert.info/pmwiki/uploads/Kilon/bgl_error_1.jpg

the file menu is transparent ??? and the small 'lady' is the wrong
picture???

That is a bug or not knowing enough about pictures space in Blender (2.63,
Vista, yesterday compiled)
