Sorry for your losses Frank. Personally, I think you ARE doing everything right. You've just had some bad luck with jumpers and that overflow. I'd have one less chromis if I wasn't standing right in front of my tank when it decided to jump. It landed on the partial glass top I have and laid there motionless. I quickly pushed it back in the water and it was never any worse for wear. After nearly two years, it's still alive and kicking. Sometimes you get lucky... sometimes you don't.
It sounds like your overflow could use a bit more protection or guarding. I don't have one on my tank, so I'm not much help there. But I'm sure others will pipe up soon with some ideas/questions. If you can post a picture of your overflow setup, that might help things along.
