It's working for me on the following versions:
Client Version: 6.0.8_GA_2661
Client Release: 20100820050930
Build Date: 20100820-0516
Version: 2.0 (build 10514)
Granted, I'm a bit on the bleeding edge being inside the company but nothing should be significantly different between our 6.x versions to cause these issues. I have taken a few liberties within the zimlet code to automate some of its functionality, though. Perhaps those "hacks" are not behaving properly on your system.
