I clicked on something @ the top of the right area & everything disappeared from there

Hi Guys,
I just finished a 21 track list with the usual columns: filename, Title, track #, composer, album, genre, year, etc. and I wanted to do the SAVE and
I wanted to check something in Explorer. I came back & clicked on something in the right side work area & everything went blank. I didn't lose it— it's still on my hard drive. I shut down MP3TAG & started it up again, but it still doesn't show anything. I fooled around going to each of the folder levels, but that didn't help.
I took a screen shot, you can see where it's empty, but my normal columns don't show up at all. Only 4 column titles show. Can you tell me how I can reset it so I can do the SAVE on it and get back to normal.
This is embarrassing. Thanks for your help.

Gratefully,

Aileen

Check the status bar to see how many files you have loaded and how many are displayed.

Then press F3 to toggle the filter and see if that helps - it could be that you have accidentally applied a filter.

The status bar is in the bottom/right of the window. This is cut off in the image you posted in the first message. As @ohrenkino has already mentioned, it s most likely that you have typed something into the filter bar. Even a single space will have an effect.
