Can't run Slim Browser [RESOLVED]

I was running Slim Browser when I had Zone Alarm but it won’t run with Comodo. I tried reinstalling the browser, redoing the settings on Comodo with no success. The applicaions control display shows Slim Browser as being allowed but I get a message "access denied"Unable to link to the web page rquested. Internet Explorer, Mozilla, Opera, work fine.

The problem was that I still had the Zone Alarm files on my drive. Once I uninstalled the program Slim Browser was OK.
