A new framework won't solve the problem

One of the recurring tasks as a software developer is to fix bugs on tools that have been designed for an earlier time. You may get a project that was written in PHP 4, or a JavaScript tool that still tries to sniff for Netscape. It is easy to see how outdated the tools are and try to upgrade them. Most often than not, the task turns into a complete redesign rather than a bug fix and it ends up costing much more time than originally planned.
