Find image in image fails

I'm trying to use the Find Image within Image feature of TestComplete but it always seems to fail. I have tried this with some very basic images but still can't get it to work, and I'm wondering if I am doing something wrong. 

I have the following basic Python code for this:

def FindImage():
  PaintImage = Aliases.Sys.mspaint.wndMSPaintApp.Picture()
  Log.Picture(PaintImage)
  CompImage = 'C:\\tmp\\tmp.jpg'
  rect = Utils.Rect
  rect = Regions.Find(PaintImage,CompImage)
  if rect is None:
    Log.Message("Not Found")

I originally tried to get this to work on a web application I am testing, but tried to revert to something very simple when that kept failing. I tried to just create a basic image in MS Paint and then took part of the image and tried to search for it. You can see the images here: http://imgur.com/a/uuz6F

I have tried debugging it to make sure that both images are actually being loaded successfully, and I can see each of the objects have the correct values in the Locals Panel. However the rect object is always empty.

Is there any reason that this should fail?
