It is possible.
First of all it appears to be prone to selecting multiple stars or globulars to focus on and I have also found that it sometimes selects an area devoid of stars.
In my experience it appears the initial selection that is used to create the subframe is too often fooled by small globulars and multiple stars but they can still be used to focu, even though it takes longer.
The major part of my issue, and one that does not happen all the time, is the star that is initially selected is not being used to perform the focus, it seems to decide to use another even though the original star is centred in the subframe. Another hint is that on occassion the square is a rectangle, which leads me to believe a variable is being corrupted.
This seems to have been introduced sometime in the last 6-12 months.
