Some of the files I have uploaded to Sky Drive at one computer are not visible or accessible at other computers and vice versa.  The problem doesn't seem to occur with Word files, but does occur with some picture files, publisher files, music files, and excel files.  In one case, the excel file was only partially there when viewed on the other computer, but is complete when viewed on the computer which originated it.  I have confirmed that these files are on Sky Drive, and I am using Sky Drive when trying to view on the other computer.  What is going on?
