My Windows 95 era copy of the Expositor's Bible Commentary no longer works in Windows 7. I recall purchasing the series for $85 back in the day. If I want another electronic copy that does work, I will need to pay $130 to order it from Logos, but that is more than the series is worth to me. If I had the 12 volume printed edition, I would still have access to it... Goes to show the wisdom in Bibleworks' frequent admonitions "to think carefully before building large electronic libraries."
