Is it possible to create a modal dialogue box, with this module? I don't mean a message-box pop-up type window. I don't think so, or at least my understanding of a modal dialogue box might be wrong: It's a window that the user must respond to so that processing in that application can continue, in particular, the user cannot click the apps main window and just ignore the dialogue box, although if the user chooses, he/she can click onto a different application. I've tried various window styles copied from the GUI-samples as well as some from MSDN, but no joy. Ian.
