ACDSee. It took a moment. I've downloaded the free sample and instantly became afraid. Afraid my brain won't understand anything bigger than X-Tree file management.
Then there was that bloke. He's a photographer, and waves his hands about. Within three minutes I wanted to chop them off, and I'm a person that helps spiders out without hurting their little feet. I'll have a bash without his help.
I haven't said thanks yet, but that's only because of the fear.
