SL does not like French filenames
Just spent half a day trying to figure out why on my French SL course the Resources links to documents did not work. I finally diagnosed the problem to be the accented "e" in the file names. Once I changed these the links worked fine! I am posting in case someone else runs into the same problem.
On a positive note, I discovered the language drop-down on the Text Labels. Nice touch! I only wish I would have discovered it at the beginning of my project.
