This problem is already in the forums since last summer:
<blockquote>"I also notice that when I click sleep mode the monitor shuts down and locks the computer up to where I have to do a hard boot. If I disable ZA reboot and then go into sleep mode everything works fine... "</blockquote>
I have the same problem with 7.1.078 Free Zone Alarm for Vista, which I believe is the latest version. When my laptop goes to sleep mode, 1 out of 5 times it freezes after monitor shuts down, so I have to shut it down by holding Power button for 5 seconds. OS crushed few times after that. If I don't shut the laptop down with the Power button it eventually restarts with "Blue Screen" notification in Vista after restart.
The same thing happens with Hibernate mode.
With ZoneAlarm closed down (not in the memory) the problem never occurs. I stopped using ZoneAlarm because of that.
I found numerous references to this problem in the Internet so I believe ZoneAlarm people are aware of this problem.
The laptop is Toshiba U-300
Operating System:Windows Vista Home Premium
Software Version:7.1 (Vista)
Product Name:ZoneAlarm (Free)
