From the D'oh Department

This must have been a serious computer meltdown!

The production of Monday's print edition of the Chicago Tribune was delayed significantly because of an extended computer system failure Sunday night.
Many subscribers therefore will not receive their Monday newspaper until as late as Tuesday morning. And the content of Monday's edition was reduced.
The Tribune deeply regrets the inconvenience caused to our customers. Timely, reliable service is a top priority. On-schedule delivery will resume Tuesday, and all Monday subscribers and advertisers will receive credit for the curtailed edition.

The Tribune's art department uses Macs, perhaps their production system should switch too!
