[ OutPost ] PROBLEM: PC reboot !!!

Hallo,
I'm with OutPost Firewal 4 Pro.

While surfing,
suddenly,
it causes my PC to reboot !!!

In example,
this incredible behavior happens
every time I go to:

I'm with Win98 SE, IE 5.5, ADSL connection,
US Robotics 9112 modem/router

If I use Norton Personal Firewall 2004 all is OK,
so the problem is with OutPostFirewall

Note:
If I use the old AtGuard 3.21 firewall
I have the same PROBLEM !!
