If you reverse the fields' default sort order then you also reverse the meaning of the SortReverse argument. Since I have reverse the default sort order for the date columns, the buttons in my context menu were named to reflect that and will be the wrong way around if you haven't also done the same.[/quote]
OK, you're confusing me now (not all that difficult actually )
I have not modified the date sort order as depicted in your post showing the Preferences window (timed at 13:45). Mine are still set at the default i.e. not reversed.
All I did with your context menu was change the SortReversed switch from Off to On and Off to On for the two items respectively (Newest first and then oldest first).
The menu items works as you have named them. Thinking about it, it should have worked when I just changed the default sort order to reversed in the Preferences screen - shouldn't it?
Hang on, I'll have another play and see what happens ... OK, I've figured it out. I was setting the date (modified) as opposed to date/time (modified) in preferences. Now that I have selected reversed sorting in preferences for date/time (modified), it now works as you have set it to.
That was fun
