Context Menu on Mac Inconsistent - Right Click doesn't select item in bottom panes (as expected), but does in top

[Rob Moss]

I expect right click to select an item and then give me the context menu for it.

That's how it works in the upper frames, but not the lower.

In the lower, you have to left click an item, then right click it.
If you left click an item, then right click on another, the context menu relates to the first.

I nearly gave up using Filezilla because I was right-clicking to select view/edit, which was greyed out unless I left clicked first.

I hope this makes sense
