Public bug reported:

Attempting to scan a previously saved screen capture.  The screen
capture contains multiple (similar) blocks of data.  Each block contains
three fields. Field 1 is a unique identifier, Field 2 will vary and must
be ignored, Field 3 contains the content that will pass/fail this test
step, but that content can also appear in other blocks of data.

Desired Algorithm Pseudo Code:
full_block = Pattern( "image1.png" ).similar(0.70) # image of block to find
field1 = Pattern("subimage1.png").similar(0.95) # a sub-image of image1.png, can uniquely identify the block
field2 = Pattern("subimage2.png") # sub-image of image1.png, a field to ignore, we won't do anything with it
field3 = Pattern("subimage3.png").similar(0.95) # sub-image of image1.png, important field (can exist in multiple blocks, but we're checking to see if it exists in this block)

f = Finder( "path\previouslyCapturedImage.png" )
f.findAll(full_block) # search previouslyCapturedImage.png, will return multiple matches 
while f.hasNext():
      current_match = f.next() 
      if current_match.find( field1 ):
            # We've uniquely the block, check unique identifier field1
            if current_match.find(field3):
                   print "Correct information found!"
            else:
                   print "Incorrect information found!"
            # We can exit now because we found unique identifier field1
            break
      else:
            # no match on unique identifier field 1, this means current_match is a different block, so skip to the next one
            continue

This style of code works when using the Screen as the target of the find
commands, but doesn't appear to work when using a previously saved image
of the screen as the target. Any ideas on how to accomplish something
similar? If my example isn't clear enough please let me know.
