I just had a similar experience yesterday, flying Bidford back to Sussex. Getting airborne PAW came up with an alert of traffic 0.1m at our 3 o'clock. as we climbed that became 5 o'clock then 6 o'clock, always staying 0.1m distance, all the time with the large black bar similar to you have shown above with the warning. That stayed our entire route with a small red aircraft symbol superimposed above our symbol, but in reverse. After landing it all disappeared. Of course, after a short while from departure I figured this was a fault but the large black bar was annoying and hampering my Skydemon screen. With a turbulent flt anyway I could not find how to get rid of it. Most frustrating. I've got a permanent installation but when I get back to the airfield this week I'll get the flt track log and send it to Lee. Meantime I'll be contacting Keith to see what he has to say. I've only had PAW installed and running for 2 weeks and have had several issues which has severely dented my faith in PAW. Currently not sure the investment is worthwhile as I don't trust it.
