Open Rico / Prototype JS conflicts?

Hey list,

Currently I'm writing a webobjects driven CMS using some ajax  
elements. I've been using the prototype library mostly for the  
ajax.updater call, for an ajax powered editor. Recently I added the  
rico library for some of the stylistic effects (rounded, and position  
moving). But it seems using Rico has broken my ajax.updater calls (if  
I remove rico, the calls work again). Wondering if anyone else has  
had this problem, or has made the two work fine in WO together.
