Comment 8 for bug 1573466

The Matching Preview internally uses findAll(), to get the list of possible matches.

The internal use of the OpenCV matchTemplate with findAll() is slightly different from the way it is used with the normal find ops (find, wait, exists and the indirect use in click(), ...).

This might have effects, when you use similarity scores having more than 1 decimal (e.g. 0.95)

This will only be fixed in version 2 later this year.
