v5.3.0 (2012-02-04)

  • Fix fatal bug: Direct-IO disks using Invisible Memory may be corrupted after hibernation. The associated image file will be also corrupted.
  • Fix bug: image files or substance files cannot be loaded during computer boot-up if these files are located on external (USB etc.) disks or Dynamic disks, or on partitions of which file systems are not same as boot file system.
        * It is not recommended to specify image files or substance files on above-mentioned disks/partitions, because these disks/partitions get ready a little later than normal ones at computer boot-up.

  • Fix bug: cannot successfully create hybrid/file disks or a ramdisks associated with image files on rare computers.
  • Fix bug: characters in wizard/property dialogs are overlapped on some non-English Windows.

        Allow to automatically move files from mount points to target paths when creating junctions.
        Allow to automatically copy files back from target paths to mount points when deleting junctions.
        Add history feature.

  • Pre-set default file names for image/substance files in the disk creation wizard.
  • Other minor improvements.

v5.2.0 (2012-01-09)
