I've been using the beta since it came up and upgraded to 1b. Recently (after having made no changes to my computer or installing anything new) an error msg appeared stating that it was unable to communicate with the kernal. No icon appeared in the tray. Under 'services' I can see the app trying to start but it hangs at 'starting'. I'm using Vista. I attempted uninstalling/reinstalling, reg cleaning etc. to no avail. I have very few things that load at startup (Acronis, ATI drivers, mouse drivers - no other programs). Once reinstalled the system loads once or twice without an issue but the failure to communicate message appears after that on startups. btw, loved the software when it was working. Any plans on inc. parental controls/root kit scanner in the final? Any plans on changing the GUI or is this pretty much set?
