Hi all, some months ago I wrote version 1.3 seems to work fine, but later I experienced some probs, now I am using 1.4, on 2 pc's with win xp, with both I got problems after a few hours using version 1.4 and recording flights, then after a while on both pc's I could not use radarbox anymore because the radarbox screen freezes, and I had to shut down the program with windows task or other programs like processexplorer, ( both pc's are fast and well configurated) I hope there is a solution. Best regards to all
