Why This SysMon Behaviour?

When I Open SysMon there is a visible window (outline) that shows and 'flashes' for a nano-second and that's it... gone.

Win11 and Canary IB both exhibiting the same behaviour.

    The behavior you're observing with SysMon, where the window flashes briefly and then disappears, is likely due to the way SysMon operates as a background service rather than a traditional application with a persistent user interface. SysMon is designed to monitor and log system activity, and it does not provide a user interface for interaction like standard applications. Instead, it logs events to the Windows event log, which can be viewed using tools like Event Viewer.

    If you want to configure SysMon or view its logs, you might need to use command-line options or check the event logs directly rather than expecting a persistent window to remain open. This behavior is consistent across different versions of Windows, including Windows 11 and Canary builds, as you've noted.

    If you need further assistance with SysMon configuration or usage, please let me know!
