5. When I Profile Document (F4), why does it tell me I need to QA the document/batch pages?

This is because you have ticked the Operator must QA option on the Profiling tab of the Job Admin form (F6).

This option works in conjunction with the 'Auto Profiling' and Output 'Auto Naming' options.

With this option enabled you'll need to QA (view) the prompted pages in the entire batch before profiling is activated.
