I used the latest D/L of URLSnooper w/latest Firefox (18.104.22.168) to find hidden URL's of cartoon episodes for my daughter. Everything worked fine for a few days - copied the mms:// links to Flashget and they all came in fine. All of a sudden, with no obvious changes to my set-up, URLSnooper began to freeze and then close when I attempted to copy a URL to clipboard. The sniffer and filter worked fine. I thought that maybe it was a timebomb type of restriction due to the fact that I hadn't registered and received my free license key. I applied for a key, tried to open the help menu to paste the key, and URLSnooper froze and closed the same way. I've tried uninstalling and re-installing, updating WinPCap to 4.1, reverting to an earlier version of Firefox, and even the Borland Registry Key edit mentioned in another post. I love this program - found similar but not better. I'm not a noob, but I'm out of options. Please Help!
