In V6 I dont like: screen refresh rate if i set it 1sec the parh vector is moving in other direction than the plane target.tineout flight if i set it less then 5 sec some flights apear as timeout flights. and some other problems. Who created the software did not pay attention on all details. The old version 3.13 and 4,03 was more accurate, the only problem there was duplicated flights. all other details was accurate. Thank you Alan :)
