Strange Grouping In Save-As Dialog

Question

When I open a Save-As dialog in a number of different programs, I'm getting a very strange grouping I've never seen before:

The files are grouped in chunks: Other, Q-Z, I-P, A-H and 0-9.  This just started recently and I have no idea how or why it started.  More frustrating is that I can't figure out how to turn this off!  The only thing I can see that might be doing this is in the top right corner, the View Menu icon, when I click on it, the item Auto Arrange is checked but greyed out.

Any ideas how to turn this off?

Thanks

Answer 1

Right-click over a blank area of the file list in the SaveAs dialog,

Hover your cursor over the Group by entry,

Select None.

Answer 2

Wow.  Never knew those right-click options existed in a dialog.  This has been driving me crazy!  Still don't know how they got that way, but all is back to normal.

Thank you so much!
