Hello
I use MDI to display multiple vis' front panels on the parent panel.
When I click on the control in the main vi A, its front panel will become transparent, the parent panel B will pop up, and B will display multiple vis' front panels. When the master B is closed, an "Exit" command will be sent to the child vi through the queue, and the child vi will exit.
But when there are many child vis, for example hundreds of them, when I close the parent panel B, the main vi A will redisplay, but the program will busy for a few seconds. Windows task manager show the CPU load is relative high than normal.
What is the cause? Is it related to MDI?
Thanks
