[1.0.1] Finder: seems to only find one match

I am using Sikulix 1.1.0 (2015-01-16_01:00nightly) on win 7
I try to implement the codes on example 2 of http://doc.sikuli.org/finder.html

f = Finder("stars.png")
img = "star.png"
f.find(img)
mm = []
while f.hasNext():
    mm.append(f.next())
print f.hasNext()
f.destroy()
print len(mm)
for m in mm:
    print m

The result is supposed to be 5 matches. However, I only get
1
M[30,32 23x23]@S(S(0)[0,0 1920x1080]) S:1.00 C:41,43 [0/0 msec]

Please help.
Thanks.
