I am NOT a techie -- obvious:

Over a couple years of using Photo Gallery, part of Microsoft Essentials> At the far left, there was a column that listed all my Picture files - just the same as what I see when I  simply open My Pictures. Photo Gallery opened this way and stayed this way.

It disappeared. That whole column. I don't know how to get it back and how to ENSURE it won't disappear again when I do.

PLEASE SOMEONE - help!!!

I find it very hard to navigate & use Ph Gallery without this.

Thanks you.
