Refresh window, what is it for?

[fbaggy]

I have just installed the latest version of fetish and been playing with the custom windows included on Fetish Central but have been unable to make the refresh window do anything. It just stays black.

I have set it to Defiler and tried casting the listed spells, I have edited the spell names to match exactly those in my spell book (IE included the VII, VIII etc ) but still nothing happens,

What is the window supposed to do?

and what am I doing wrong?

Cheers in advance
