I just installed the new True Image 2010 Build 6029 and tried twice to do an incremental backup, based on a full backup from the previous version of 2010. Both times the result was that the system became completely unresponsive to any keyboard input or mouse clicks. The only way out was to cut power to the system.
The previous build of 2010 worked fine, except that the computer would go to sleep during full backups. After uninstalling Build 6029 and re-installing the previous build it works again.
