The problem lies in a small javascript file: brwsniff.js, a handy dandy browser sniffer that checks for the installed Flash Player version number. The bit of code written for non-IE browsers wasn’t expecting a player with a version number of more than one digit; so, seeing only the one’s place digit, if you’ve got Flash Player 10 installed, the script comes up with a version number of ZERO!

Unfortunately, the author of this otherwise delightful script has not updated the file since before Flash Player 10 was released. Having made the minor repair necessary, I’m making my updated version available for download HERE.

Please note: If for some reason you needed this script to detect the browser software in use, I’m afraid you’re still out of luck. The script seems to see everything as either IE or Firefox.

[UPDATE]
Got a message from Pau Garcia i Quiles, author of jsbrwsniff.  He’ll publish a bugfix soon—until he does, download the version posted here.  I’ll announce when an official bug fix becomes available.  New features he’s planning to add in the coming months:
