After installing Adobe Reader 8.1.2 system restarts and locks up.
I have Windows XP SP2, plenty of spare disk space and Adobe Reader 8.1.1.
The 8.1.2 Reader appeared to install OK and asked for the system to be restarted. When I accepted this it shut down and rebooted as expected,
but just before it was fully restarted it froze and I could do nothing.
I pressed the power switch and tried again but the same thing happened again.
To get back to a usable system I had to boot in safe mode and go back to a restore point.
I don't know if this is relevant but it stopped just before Norton firewall usually starts.
I am keen to install the new version because of the security fixes.
