RORO01  How can anybody give five stars to a beta application? Just thank the developer for thinking of us and be patient. Hopefully the time will come for a five star rating.

PHILIPZ  Not sure if I understand your comment. So you can only give good ratings if it is a non-beta, no matter how good/reliable it is?

HENRIKTEKNIK  If MacUpdate provides a voting function during applications' beta stages, then of course the users should able to post their review scores, should they feel for it.

Ratings during an app's beta stage, should reflect the reviewer's experience with that app, at that particular moment in time. If an app is good, it's good. I don't necessarily think it stinks just because it's in a beta stage. Mind you, some developers tend to keep their apps in beta stage for very long, sometimes even if it's to be considered final. If that's the scenario with an app that I like, then I usually won't hesitate from giving it the rating I think it deserves.

RORO01  Five stars are for perfect applications whatever they are. Normally beta applications are not perfect by definition.

PETER DA SILVA  Why would a TCPDump (or rather libpcap) GUI "not be a real sniffer"?  
(Version 0.46.5)

JENSF  CPA is able to open pcap files. so you first need a pcap file. you can create one e.g by using tcpdump in terminal (tcpdum -w file.pcap)

BOZO CLOWN  Just choose File / New Capture from the menubar when the app starts and it'll appear. Arguably, the app should do this automatically when it starts.
