No errors are printed but the map essentially becomes unresponsive. I thought it was just an error with a TCP RTL connection at first but it's doing the same with the USB directly plugged into the computer.

i also see a high load on my pc, and it takes quite some time until aircraft appear... could this be performance issue?

looking further: the client always imports all (7000!) airports and puts them on the map, just hidden if the airport is too small for the zoom level... Just showing the airports in the map region, would help performance.
