My friend bought a copy of ps7 from where his dad works (it cost 125$). The problem is, it says photoshop 7b on the box, where as regular photoshop doesnt have a B after the version number. I am either thinking this is a business version, or a beta version (highly unlikely to be boxed tho). It appears to have all the features of photoshop 7. Can anyone provide any insight into this?
