I've been playing with beef and ettercap, and I've been able to dns spoof my test machine into clicking on my beef hook, and I get a message in the beef log that a zombie has connected and gives some useragent info about it, but the zombie never appears in the zombie column on the left (or in the zombies menu, sometimes localhost will only show up there).

I've had this problem with both chrome and firefox as the victim browser, I get the feeling this is something simple but I can't figure it out, anyone seen this before?
