Hey,
 
 When I run this example and press the letter 'a':
 
 [phil@localhost examples_pygame]$ python blit_blends.py
 press keys 1-5 to change image to blit.
 A - ADD, S- SUB, M- MULT, - MIN, + MAX
 one pixel is:[(99, 0, 0, 255)]:
 press keys 1-5 to change image to blit.
 A - ADD, S- SUB, M- MULT, - MIN, + MAX
 Traceback (most recent call last):
   File "blit_blends.py", line 163, in ?
     main()
   File "blit_blends.py", line 77, in main
     im1.blit(img_to_blit, (0,0), None, blits[event.key])
   File "/usr/lib/python2.4/site-packages/pygame/surface.py", line 199, in blit
     _surface_blit(self, source, destrect, sourcerect, special_flags)
   File "/usr/lib/python2.4/site-packages/pygame/surface.py", line 1155, in _surface_blit
     result = _software_blit(src, srcrect, dst, dstrect, special_flags)
   File "/usr/lib/python2.4/site-packages/pygame/surface.py", line 1347, in _software_blit
     dR = array.minimum(dR + sR, 255)
 TypeError: function not supported for these types, and can't coerce to supported types
 
 Thanks!
 Phil
