My Director 11 shockwave files will not run on a Mac with OS X "Tiger" 10.4.11.
With the older plug-in (10) I get an alert that the browser cannot open the
"new" format, and it asks if I want to install the newer version. Yet when I
install the most recent plug-in (11), I get this alert: "The page [xxx]
attempted to load an internet plug-in named "Shockwave for Director", but the
plug-in failed to load successfully."

What gives? Adobe's right-hand (Shockwave plug-in 11) does not know what its
left-hand (Director 11) is doing? Am I to assume that any and all Director 11
shockwave files will henceforth only run on Macs with Leopard, and not with
Tiger? This is unacceptable!
