I currently have a QT 3.3.6 application (yeah i know old) that needs to have the capability of opening up a QT 4.7 application. The issue is the QT 4.7 application is minimize to the QSystemTrayIcon when I'm tryign to do so. Currently the QT3 application can open up the QT4 application but there is no GUI and it's just a gray box. Any ideas?
