[OS X TeX] Problem accessing a .sty file command?

[Christopher T. Allen 95]

Thanks so much, Herb! I hadn't reset all my script/engine stuff. I'm not as 
embarrassed as I might have been because I had exactly the same failure after 
resetting the scripts. However, quitting TeXShop and restarting it afterward 
solved that problem. I'm not sure why TeXShop doesn't switch script/engine 
stuff when you ask it to and instead waits until after quitting, but I can accept 
that.
