Hi, I just did an upgrade from 4.5.5 to 5.0, initially the Zimlets did not appeared at all, but reading the forums it was apparent there is a bug and they need to be redeployed after an upgrade, so I redeployed them, now the zimlets appear in the left pane but the do absolutely nothing.
The Zimlets are kind of a work in progress.
For example, I don't think any of the Zimlets that change the minical work because of our switch to Lazy Loading.
