After working happily for years, my IrfanView seems to be corrupted. Or maybe it's a memory issue ?
When I save a photo that I have worked on - usually crop or rotate - the result takes much longer to save than before and the resulting colours are posterised.
Anyway, I'm thinking of buying Photoshop Elements but it's hard to find what exactly it will do. I know it does clever stuff with layers etc but will it do the simple stuff like crop, rotate, resize, correct verticals, red eye eliminate, etc ?

Yes it will, is the short answer. You won't get all the Photoshop features with Elements but it will do the things that you want it for.
