Drive lists Z to A

I made a few changes to the configuration of DOpus yesterday. Today when I loaded it, my D drive lists things Z to A, it's real annoying. All the other drives sort A to Z. I've looked to see if I can find what I've done but I just can't see anything. What could the problem be?

Click the name header to resort it in the other direction.

Yes but every folder I open is sorted Z to A. I want it to be A to Z all the time.

See Folder Formats: Quick Guide for information how to change it permanently for that drive.

Thanks, that did the trick.
