When I create a packet filter and I put in some bad info (Missing part of an IP range for example) it flashes a red box around the incorrect entry.
If you forget to put in a name, it does not flash this box and it lets you save it. You get a jiberish name and the filter sometimes disapears after a few seconds.
I also tried this on the demo version and it does this to.
Bug or poor user intreaction.
