Have been running BibleWorks 4.0 on iMac with PowerPC using Windows 98 for years. Am thinking of going to a Mac Laptop. Has anyone successfully used BibleWorks 5 or 6 on an iBook (or PowerBook)? If I replace the iMac with an iBook, will I need to upgrade PowerPC in order to run a more current version of Windows to get the most out of BibleWorks? Appreciate your advice.
