OK...an idea...
Rename all your existing brainfile extensions EXCEPT for the newest one (TAWNYA).
You'd have something like halbrain.dbx, halupgrade.dbx, etc. or whatever you choose for an extension.
This way you can tell if Hal is pulling from the newest one because it shouldn't be able
to access the non-standard extension.
You can always rename the extension(s) back to their original .db status.
