\r\n1.launch app on device (start in landscape or portrait), file\r\nattached, but code copy pasted below
\r\n2.use your finger to drag the grey square to a new location
\r\n3.use your finger to press on the object then quickly make a\r\ncircle. repeat if need be
results: on the second (or third) try, the object will not track\r\nwith the users finger. This does not seem to occur on the first\r\ninteraction.
