Under Windows, many user actions can interfere with real-time processing. The actions in the
following list suspend the processing of events.
• Moving and sizing top-level windows
• Bringing down the System menu
• Pressing the <Alt-Tab> key combination
You can prevent these user actions from interfering with event processing by doing all of the
following.
• Call DisableTaskSwitching (or use the alternative for Windows NT mentioned in this
section).
