No, not really. The keyboard handler is integrated into a command line tool that shall be simply called from the command line. For convenience, in order to avoid on Windoze the suffix ".pl", I would like to call the tool from a little batch similar to the example. The console handler even refuses to respond, when started in a new window. It appears that the keyboard is somehow still linked to the old window.
Anyway, thanks a lot for the hint!
