[nabs-l] dropbox problem

[vejas]

Hi,
Many of you have probably used drop-box before.  I use it on my 
i-phone and there is a problem that I seem to have when finding 
new files.  I use this site primarily for Spanish.  I downloaded 
my Spanish folder onto my Dropbox a few months ago.  For some 
reason when I log into dropbox and go into my folder, new files 
my teacher just posted don't show up and only the old ones do.
Has anyone had a similar problem?
Thanks,
Vejas
