Vendor Status:
Response: "Thank-you for bringing this issue to our attention. We have fixed the issue in our newest release 4.0. Some file space allocation growth functions were not "zeroing" out new disc space as the file grew. Unused blocks were being captured into the form data, along with any data that may have resided on that location of the drive. The complete file growth areas are now made null to avoid any unwanted data from being captured. It may be worth noting that this does not occur in Windows XP, as the operating system takes better care of this on its own."
