Hi Hamilton,
I have AjaxHelper version 0.3d installed on an OpenACS 5.1.4. I followed the portal mashup tutorial to get the fading effects for portlets however in doing so it has become impossible to modify any custom portlets. Something to do with the JavaScript libraries conflicting with the JavaScript HTML editor - it gets rather messy and crashes the browser (Firefox and IE)? Thought I'd let you know as it could be a major bug for anyone who uses custom portlets.
