So it turns out the reason my QT movie didn’t work properly under IE/Win is because MS burned Apple with the release of IE 5.5/6 by dumping the old Netscape plug-in methods. Nowadays you have to wrap your embed tag inside an object tag, and set all the parameters identically for each. Fine if you find out, but I feel sorry for all the people with legacy QT content online which suddenly no worky no more. Anyway, the trapeze page should work for everyone now. Sorry about that.
Got my UC Berkeley staff ID card today, which meant I was able to order BBEdit at an educational discount (you have to fax proof to BareBones).
