I have a very strange problem. The application is based on Qt C++. There is a TabWidget whose tabs are created dynamically. The tab contains QtMainWindow in ActiveX widget. When multiple apps are started, the selected one works fine. But when another tab is selected, it becomes unresponsive. When I minimize the Application and then maximize again then the tab starts working fine. I tried with setFocus, activateWindow, showNormal and setActiveWindow but nothing is working.
Can somebody help me in this issue?
