BTW - when re-building project file, VFP automaticly closes procedure file opened with set proce to myproc.prf ( tried & works ). But, just a question, when it says, that your app file is in use ( never saw error message like this ) how do you quit from your application? It's just a guess, is there clear events at the end? Just thinking why it uses it... hth Dezider
