I use Acronis True Image 11 on XP Pro x 32 SP3 machines. I attempted to backup my machine several times using ATI 11 today, and the application would hang before beginning the backup. Almost immediately after ATI hangs windows will stop responding as well. Explorer would stop responding, and no application would function. The only thing I could do is move the mouse cursor on the screen. Each time I would have to do a hard reboot. I'm attempting to create a backup image of my machine to an external drive using ATI 11. I believe the problem is NOD 32 V5 AV is causing ATI 11 to hang when attempting to communicate with the external drive. I did not have this problem until upgrading from V4 to V5. As soon as I uninstalled NOD 32 V5 Acronis ATI 11 allowed me to create a backup image of my machine to the external drive with no problem. I have gotten no BSOD, but if I attempt to make the backup image with V5 installed the only way I can use the machine again is to do a hard reboot. Task manager will not even work to kill the ATI process. Is anyone else using ATI 11 with V5 AV on XP Pro x 32 SP3 , and able to create backups to an external drive? I'm pretty sure this is a bug or incompatibility issue.
