First off, I'd like to say, I'm impressed with this NetFlow Analyzer! Its very nice! Easy to install and to get working right from the download. I'm looking at your Beta Version 5 NetFlow Analyzer and I have a question about adding IP groups. Is their a easier way to create groups of IP networks under the IP Group Management GUI other than through this GUI? i.e can I create IP groups by importing from a csv file? I found that I can only add 15 subnets to a group. If I add a 16th network to a group the page blanks out on me. Is 15 subnets a limit?
