Robert, I want to present a message (osg::Text) to the user just before I do a osgDB::readNodeFile on a visual database. I turn the switch on to show the dialog right before loading the database. The dialog shows up only AFTER the database has been loaded. I just want to hold off loading the database until the dialog actually shows up. What do you think I can do to accomplish this? Sorry to take your time on this.

I'd recommend just going through the OSG examples. Try the run_examples.bat as a way of running through them, press escape to exit each app and move on. Robert.
