When user is waiting fairly time consuming SQL query to finish and application crashes (halts without a trace but that's a another problem) for some reason, database connection might leave table(s) locked. This will cause said table to be unreadable (without dirty read) until database server is restarted. I thought that any and all database connections will be disconnected and any possible locks will be released when application crashes but that doesn't seem to be case. Do any of you have any suggestions how to track down and solve this problem? Database backend is Microsoft SQL Server 2014 Express and I use FireDAC access it. uniGUI version is 220.127.116.116 (Complete). // Mika
