I'm trying to download lessons so I can view them during my lunch hour (work wouldn't like it if I viewed them there!). But in the Fundementals 1 lessons, downloading a few of the lessons is not working. It kills both Firefox and Explorer. Is there a known issue that resolves this issue?

Or even better, is there an area on the site where I could download all the lessons of one area in a single (or multiple) zip files?

Thanks in advance for the help!
