Using stackFiles

[Dar Scott]

I'm having trouble using stackFiles in a standalone.

In startup of the mainstack of the standalone this is put into 
stackFiles:

alice,filters/alice.rev
betty,filters/betty.rev

...then later in startup is this:

start using "alice"

...and an error is thrown.

The standalone and the filters folder are in the same folder.

What am I missing?

(I read that stackFile paths are relative to the location of the stack, 
which I assume is the standalone in this case.)
