Activity.nsf complaint from a server/org I no longer use

Each time I start one of my two Notes clients (one on Linux, the other on Windows) I see this message in the status bar :

“The widget catalog from server Someserver/Someorg will not be used because there were errors creating local replica for activity.nsf”

No big deal here but I’m curious because I’m now User/Otherorg or Admin/Yetanother and I have now very little to do with /Someorg and there is no way my Notes clients should attempt any kind of business at startup with Someserver/Someorg.

I believe there is some kind of configuration residue somewhere that prompt my client to try and get a replica for Activity.nsf from Someserver/Someorg, but I can’t figure out what or where.

Does someone have any clue ?

Thanks
