[HJG] I'm not sure if this is a bug, so here is a demo for a problem with console on Windows,
when the main toplevel window is not shown, e.g. with [wm withdraw], so that its close-button cannot be reached.

Exiting the program via the close-button of the console leaves a running wish85-shell behind. 

To get rid of them, you need to use the taskmanager, or an utility like process-explorer.

To prevent this, include this statement with wm withdraw:
  console eval {wm protocol . WM_DELETE_WINDOW {exit} } 

However, exiting the program via the console-menu File/Exit works correctly,
shutting down the remaining wish85 as expected.

Is there a reason for this different behaviour of close-button and File/Exit ?
