Crystal Reports for Adagio should be shipping Real Soon Now! It is capable of modifying all the reports (.RPTs) in Adagio. Of course, you'd want to make a backup of the original before making any serious changes!

Look for an announcement in the next couple of weeks. Of course, Crystal Reports for Adagio is also capable of producing fabulous reports from your ACCPAC Plus data (just like Quik Reports for Windows).

Cheers
