Folders ~ Arrange By Name ~ Annoyance!

I recently had to change the default view from Name to Size when opening a

file via a programme and is now stuck like it with every programme I use to

open or save a file from. How do I get the ordering back to name?

Please note that when viewing folders in Windows this isn't a problem, it is

just when opening or saving that they are all listed by size.

It's very annoying as I keep having to reorder before I can open anything as

I can't find it!

Thanks,

Sarah
