HUD doesn't show on Mac

This screenshot is from my student's PC...
I teach Dreamweaver. It's really difficult to teach when things don't actually work on my screen. Most of my students have PCs, I have a Mac. It works fine for them and I wind up teaching on their screens. It's very frustrating. Is there anything I can do to make it show up? I won't even get into the mess with the extract panel and the CIB. I basically make it all up as I go along. So what's next - what should I be learning to teach next year (that isn't DW).
