Hi, I run Acronis True Image Home v11 on a PC equipped with Windows XP Pro SP3. The client software performs splendidly in all respects - until I have to get it to mount an image of a verifed backup tib-archive. It reaches the point during the mount image process, where Acronis confirms that "Assigning the drive letters was successfully completed". However, as soon as I click the OK-button, Acronis immediately becomes totally non-responsive, as well as causes all other open programmes to act the same. The PC locks up, and although the Windows Task Manager is accessible, it is impossble to shut down any open programme without evoking error messages. A forced shutdown or reboot (which results in data loss) remains the only alternative escape this predicament. This problem was repeated several times - even after a disk format and new software installation. Any ideas on how to solve it is highly apprciated. Thanks.
