I've had to push out a minor update to HB-Cumulus as I've just discovered a little bug which causes the HB-Cumulus settings to be deleted when another plugin is deactivated.

You can get the latest revision from the HB-Cumulus project page.

As this is a new release, I've closed comments on the 1.0 post. If you encounter any problems, please ensure you update to rev 1.1 and if the problem still exists, leave a comment here.
