4. Freecell Pro Interoperability

• 4.1. The Problem
• 4.2. The Solution

• Freecell Pro is a feature-rich Freecell implementation for Win32, that integrated its own solver (by Don Woods and further work by others).
• I wanted it to integrate Freecell Solver as well, so I was referred to its developer, Adrian Ettlinger.
• Ettlinger was happy to help me, and so we started working on integrating the two programs.
• After some code was written and about 100 E-mails were exchanged, a problem surfaced.
