Encoutered a sharing violation

[jacques]

I started getting the following message when trying to save models:

Encountered a sharing violation while accessing...\revit009b9615-caae-40f1-a2ce-5338cbed3...

I found in different forums that this used to be a problem in Revit 2007 for shared models. None of our models are shared model. So, I don't understand why it is coming up. The problems goes away when I switch to a different window. 

Does anyone have any ideas on the origin of this problem?
