Hi Angela,

>I add read event after Do form in my main.prg and it works. But after that when I try to close the window. It's said "couldn't quite Foxpro". Why? Do I need to add something else?

First, let me ask: once you close this form, what do you want the app to do? Do you want it to close? Or reamin at a wait state at your menu, is this a top level form app or is the FP screen visible?
