Unable to access Find feature in iCal 3.0.4:
Solution to access an emergency find function:
Step one:
Download the Sunbird Calendar application from Mozilla
http://www.mozilla.org/projects/calendar/sunbird/
Step two:
In Sunbird import your exported iCal calendars (.ics files):
Your exported calendars are now searchable in Sunbird.
Crude but effective.
Exporting Sunbird's (previously iCal) calendars as .ics files and importing them into a calendar stripped iCal App window didn't restore the Find feature in iCal.But at least the data in the calendars is safe.
The loss of the Find feature in iCal is not new, it ocurred in an earlier version. I agree with others that Apple are sometimes happy to release obviously buggy - seemingly with even basic testing neglected - software. Let's hope the cure is in a very short pipeline.
