I have been experiencing a task bar freeze that can last between 5 and 10 seconds.
I get no response from start button or any task bar icon. However, the clicks are queued and are processed after unfreezing.
This has been bugging me for several months whilst trying to trace the cause.
I have finally discovered that the temporary freeze occurs only after closing some desktop windows (e.g. Apps, Web Browsers, File Explorer Windows, etc)
I later discovered that if I exit the ObjectDock Program, Start 11 no longer freezes after closing window.
Could you possibly try to reproduce this behaviour and look into what it is that causes this.
