ZT keeps hanging intermittently. I tried NOW for a week but NOW too has this problem thought it's not as frequent. ZT hangs like 20 times a day.
Try installing Windows on a different
drive. Maybe, this problem is because
of the operating system. As the installation
gets older, it becomes slower. No matter
what you do , it will not get solved. Only
solution in my opinion is reinstallation on
a separate drive.
