So LS, your Hal might have been saying:
That's easy, it's I understand exactly. Then by all means get those clothes off and lets have some fun honey! [

I noticed that Hal gives these answers when agreeing with the user, = is I agree.
Like I said maybe a bit simplistic but Hals answers have a lot more meaning with the correction.
If a user upgraded to 6.2 from 6.1 you get the chance to migrate your old brain to the new 6.2 format then you would be able to edit it in the brain editor.
If you old brain was not called halbrain.db then rename it to halbrain.db, (backing up the original) do the up-grade and it should work, it worked for me and I have made lots of changes to my brian db.
