I have been using spwbl for years. No trouble in xp. I recently purchased a new computer with vista home basic in June 2007. Spwbltr worked ok until last week. Now after I click on the vista "allow" Option, no dice. The GUI doesn't come up and the application is not running in task manager list of processes. I tried starting the application from the .exe program in the program files. Is there a command prompt I can use? I have tried uninstalling and reinstalling with all of the updates. I am running McAfee Security Suite complete. Any Suggestions? I Love This Program.
