I was running Kerio 4.2 (w/ BZ's enhanced ruleset) on my desktop (XP Pro) and notebook (XP Home). They were both running well and I was very satisfied until recently. My desktop is still running Kerio just fine but my notebook started having problems a couple of weeks ago. Here's what happens on my notebook (btw - neither computer is infected with anything): - Firewall icon does not show up in system tray - The servcies are running but I can't bring up any gui interface - I can't stop the services (nothing happens to the service when I try to do so) - The firewall still responds with pop-ups when something happens but the pop-ups flicker and take a long time to respond to any mouse clicks The notebook is relatively new and I did a fresh install about one month ago. No other firewalls are running, etc. and it had been running just fine until I started having problems (nothing changed (i.e., no new software, etc.). I've uninstalled and re-installed a couple of times. The only way I can get Kerio to work on my notebook is if I use 2.1.5 but I would like to get 4.2 working again. Any help would be appreciated.
