>I don't use ReFox myself. Could you give an overview of what the various "levels" are supposed to do?

Level I is the the lowest, you declare a value in yoru app & compile, then use refox to 'brand it' -- I think level I+ is easier & better.

Level II requires that you brand your .exe/app and the vfp dll's

Level II+ is as "yet" undocumented & unsupported.
