This is NOT comforting! I did a full backup to the Secure Zone with Build 771 on Sept 28th, 2004. I have done incrementals daily since then, the only exceptions are the days when ATI balks during an "Internal Error:Unhandled Exception", whatever THAT is (seems to happen 3 or 4 times weekly). About two weeks ago, I updated to Build 774. The "unhandled exceptions" continued. However, I just went in to do an "Explore" of the images in the SZ and guess what Even though my 40 GB SZ shows "total size=40 GB" and "free space = 21 GB", thus indicating the existence of a 19 GB "SOMETHING", when I go to "Explore" the files, TI reports there are NO FILES IN THE SZ!!! WHAT is up with THAT Anyone had this problem or something similar? Oh yeah, I also remember getting some sort of message about the TI Scheduler wanting to terminate itself in an unusual way and WIN XP complained about it. Since I got that message, I cannot run ANY backups! TI8 is LOCKED UP and I can't get it unstuck. I cannot do any manual or scheduled backups, either full or incremental to ANY location PERIOD... sound familiar to anyone? I'll be writing to support soon unless I get some help here in the forum. Thanks!
