I can confirm that as I read elsewhere, it does not seem possible to
either subclass or hook (SetWindowsHookEx(WH_CBT, ...)) a console window.

That was my thinking too - but perhaps Reini is
hinting at something that I do not understand?
No, I mixed it up.
perl2app --gui / pp --gui created apps, have no console.
So I create them with AllocConsole or CreateProcess and
redirect STDERR/STDOUT to this window, and display it only when requested.
To work around the flashing issue I can
1) create it only when requested, but then I loose the previous output,
2) or create it hidden or offscreen and show/move it when requested.
Menu: View - Messages...
But better is to create the app without --gui and hide the console as
discussed here.
If you want to start a sub-process hidden, then
Win32::SetChildShowWindow(SW_HIDE);
is probably easier :-)
Correct.
