XnView Software

I remember I used to be able to search a folder for images that were similar. However I think I either turned on a setting or turned off a setting because now I can't do it anymore. Now when I try to do it instead of a list I just get two black screens side by side and below them is a bunch of forms that are blank.

results area is hidden
grab invisible bar above 'Sort by' and drag it up

That fixed it, thank you. I was wondering what I did that messed it up.
