Hi All,

I read from people in this forum suggest not to use MDI as it is an old fashioned design. However, when there are a few windows of the app opened, it is not easy to bring them all back from the grouped task list. What I can only do now is when the “main” window is closed, I close all other windows automatically. Is there a way that I can bring up all the windows of my app in one time?

Thanks all.
