macOS version: file list box event handling works badly

Plenty of things that go wrong. Note that people either use the magic mouse where moving your finger across the mouse itself works, or they use the touch pad. I use the mouse as this is way more convenient with normal macOS use.

1. right-click and the menu shows and goes away immediately. Or it goes up and disappears when you move the mouse. or it stays up, as one expects on a mac as that is the most user-friendly thing to do. This appears to be very sensitive and it has the feel of being programmed at the lowest level instead of using high-level macOS mouse events
2. Scrolling the listbox with the mouse is not very nice. The columns do not stay in their spot, but are moving left and right all over the place. This makes looking for the problem files (bad star registration, bad star shapes and so on) a frustrating experience. It again appears being programmed at the lowest level, with any left-right movement resulting in a big change of column positions. Add this to the inability of the columns themselves keeping their user-assigned widths and the whole experience is one of utter frustration. This is probably the worst part of APP in terms of usability
3. add setting the reference frame as a right-click menu option
4. sorting on a column should be an option in the column header, by clicking on it. click again to sort the other way. Loose the sort options in the menu
