Is anyone else having an issue with -- what I am assuming is calend -- resetting the home screen (i.e. applets being turned off, status bar returning to default) at midnight?

I can go into settings > control panel > panels, hit OK, and everything goes back to the way it was, but it's an annoyance. Home screen applets have to be reselected though.

I uninstalled calend and the issue is gone, but I'm not sure if it is calend specifically or calend and some other app conflicting.
