Hang on executing usercommand defined to itself

[DrShark]

To reproduce:
1. In Configuration->Misc enter new Alias: testhang
2. Use Choose command dialog, go to usercmd.ini section, press New..., enter em_testhang
3. In next window define "Command:", put there the same: em_testhang
4. After saving this, go to Total Commander's command line, and execute either alias testhang or command em_testhang -> TC interface is locked, only way to close TC is a Task Manager.

I suggest to show an error when user tries to create em_ command which executes itself, and also an error if such command or alias to it executed from commandline/button/menu etc (will help if user edited wincmd and usercmd.ini manually).

You can also easy create loops by view modes and assigned commands
but Christian didn't want to catch such problems.

Sorry, it's practically impossible to catch all such problems. You could make chains of 100 commands calling themselves in a loop. But you should be able to abort with ESC.

Exactly and this is why YOU Doctor Shark should use the thing between your ears and not blame TC for your mistakes

You could at least make a basic check when user adds such command in Configuration (step 3 in my example): if user entered in Command field the same text as the user command name, then don't make OK button active.

But you should be able to abort with ESC.

Either it didn't work or I didn't wait long enough with my example from first post.
