Ah...now I thought of this. I already have globals that are pionters to my
dialog boxes, but not one to my main_application widget. Thing is, where
do I set it? With the dialog boxes I set the globals when the widgets are
created, but the main_application widget already exists. Argh!

Thanks for your help,
