Enable/Disable sample unable to exit ...

[bitRAKE]

There is a corner case where toggling enable and disable buttons a few times will lock the dialog - where ESC key no longer works to exit. The title bar menu and red X corner button still work to exit with the mouse.

Just experienced this on Win11 - will need to research further perhaps. Feels like a windows bug. It isn't difficult to do - timing isn't important.
