Anyone any info on the upgrade fees please? I am licensed for Bat Professional V4.2.44.2 which also allows me to use up to a certain version of V5 I believe? If I buy an uograde now will it allow use of V6 when it comes out of Alpha / Beta builds? I am hoping the well known issue of flaky Folder Views and Column Sizing are addressed? That would be my main incentive to upgrade. It would be nice if any inbuilt back up and restore abilities were more robust than V4.* too  Thanks.
