hey, that's my blog. When a dialog box becomes modal, it disables the main window of the application, unless that dialog box is itself the main window and there is no parent/owner. Since the export is displaying and redrawing, it's not a message pump problem, the problem must be that something has caused the dialog bot to disabled. I know nothing of delphi, but you need to ask, what is the main window of your application, and it is disabling its children when it gets disabled. If you intended to make a console application, and it's really set as a true win32 console application, it's possible that this configuration isn't actually supported and you may need to create a GUI application with a main window (even if it does nothing). You should refer to c# and Visual Basic (VB) examples. One of the technote actually

one of the technote actually refers to an export dialog freeze like this, but it's specific to VB
