I have had trouble since the update with the error "Diigo: A server error occurred..." popping up when I open up a new browser window. I have only noticed one effect of this. I have added a few smart folders on the toolbar, and the one that is a list comes up empty when I get this error. I know the list is still there because I can get to it from my library. Any ideas how to avoid this error and get my list back on my toolbar?

Thank you for the quick response.
