KB-34344: Close button disappears on a modal screen.

Question:

I have a modal screen set up to display a title bar and a Close button. However, when opening the screen, the Close button is not displayed. Why does this happen?

Solution:

If the option Disable task switching is enabled, the Close button disappears. The solution is to disable this option, or tocreate customized buttons on screen to close it. Another possibility is to edit this option with the application at run time by using the _top frame’s SetDisableTaskSwitching() method.
