The code:
Note that either of two dialogs can be called: first one, and then when it exits, another. The problem is the first dialog: the program processes until it enters the CreateDialog statement, and the program quietly dies inside it. Several calls are made on the dialog handler, but the window never appears. Note that it is the only window being used; there is no normal "main" window. This does not happen on my development machine; it works fine. It only happens on a clean install. I'm using Windows XP Pro, and MSVS.net as a compiler. Any ideas?
