It seems to be working and syncing fine for files that were already set to be available offline.  I don't know what changed.  Now, when I right click on a file under the skydrive folder and select "Make available offline", nothing appears to happen except that right clicking on any other item no longer brings up a context menu (if I navigate to a different folder and come back, the context menu works again).

Examination of the logs shows two events every time this happens.

I have no idea what to check next.  Any help?
