The User should not get any Window at all. Not even a mintty.

The problem is not the too-fast closing of the window but its opening in
the first place. The script above is a mere example.

GREAT! Thank you Marco!

With this I see, that the error is clearly at run2_gpl.c at line 350ff:

   if (bUseMessageOnlyWorkaround)
     {
       if (!bHaveConsole)
         {
           AllocConsole ();
           bHaveConsole = TRUE;
           SetParent ((*GetConsoleWindowFP) (), HWND_MESSAGE);
         }
     }
   else if (!bHaveConsole)
     {
       bHaveConsole = run2_setup_invisible_console ();
     }


For Windows 7 the bUseMessageOnlyWorkaround is always TRUE and as I do not
have a Console Window yet the AllocConsole() function of Win32 API is
called.

This pops up a Console Window. A DOS-BOX. And there is no help to this.
Windows 7 just goes on, fires up a Window and places a cmd-prompt inside
it. Right in your face. :(

If I comment this line with

           // AllocConsole ();

then my scripts do work as expected: No DOS-BOX window pops up. Yeee!

Though stdout, stderr might be messy then. I might run in other troubles,
since there's a reason for this call. But so far this ok for me (yet).


Thx,
Oliver
