If it hangs on connect that means it's trying to connect and waiting. It should say 'connecting' in the notices box. Obviously I need to make that more obvious.
Fetching the iRules obviously requires you have an initialized connection so if you haven't hit connect separately it goes ahead and does it for you. Apparently that's just as confusing as it is helpful. I need to add a popup dialog when connecting to make this much more obvious.
Go to file->edit connection settings to configure which BIGIP you are going to talk to.
I'll modify the original post and call it "requires java 1.6 or higher." I've run it with both 1.6 and 1.7 but haven't tested with 1.5 thanks for the info.
