I'm having some problems with my course. It includes some things that
work on my computer, but not on my client's computer. For example, I
have an Attachments tab and an Exit tab on my toolbar - these work when
I'm viewing the course here in my office, but when my customer tries to
view them from their location, a lot of stuff doesn't work. Even
attachments that I've added through the attachments tab as a URL aren't
showing up - I get an error. Can someone help?
