I couldn't say Clay.  There really are some serious stability issues going on with the Events module.  You won't get alot of knowledge about it, for whatever reason.  I would recommend staying with the old version you currently have until such time as they release a fix for these issues, which seem to be incremental per release.

I too am looking for a release that works and works well, but the earlier ones are too feature-poor for my taste.  I've been shopping around for an Events module but no one, other than Telerik, has anything that comes close to what I want.  However, Telerik's is only an ASP.NET release, not a module and I'm waiting to see whether they are planning to release a version of their new Events Menu control for DotNetNuke.
