Fighting against time last week to deliver a new version of an old project dynamic website, and my perl Modules don't print their intended output. I fought against this every way you could think of during four hours non stop, until I disabled my browser's page cache, and everything goes fine.
At this point I thank God for using CVS. This allowed me go back on every try (almost) and merge the important changes to de version I had at the beggining of my "Psicological Blindness".
