... didn't work with iCal 3/Leopard. The System Requirement notes only state compatibility with Mac OS X 10.4 and 10.3.9, but I had my hopes up because this AppleScript provides a very useful feature enhancement to iCal.

When using this software, iCal presented an error message that roughly said "the script couldn't open or didn't finish running"

I hope the author can update the script to work with the latest version of iCal.
