We are on WF5/creo. Hate it. Thinking of upgrading, possibly all the way to creo2.
What are you guys suggesting? Should we go all the way to creo2? Is the latest date code good, or is there a better/older one?
What are your experiences with it. Did I mention I hated WF5/creo? 
Hopefully later releases will be less loathsome......
Thanks!
