I tried trimming iCal on my OSX 10.4.11 Mac using version 0.95b. Being a naive user, I accepted all the default checks. I then put the backup file into the trash and launched iCal. All seemed to be working just fine, so I tried to empty the Trash, only to be told that "The operation cannot be completed because the item "iCalAlarmScheduler" is in use." Alarmed (pun intended), I tried to locate this vital item in the search, and couldn't. So I tried taking the backup file out of the trash and putting it in the Applications folder, trashing the trimmed version and re-naming the backup file as simply "iCal." This program -- ie, what I'd've thought would be the original! -- won't launch.

How can I either bring "iCalAlarmScheduler" back into my otherwise-wondrously-smaller iCal, or if that's impossible, restore the backup file?

Thanks, and sorry for being a dolt!
