I've recently installed latest x-Cygwin on different PCs and suddenly discovered strange reaction on 'system' function inside Perl/Tk apps. Naturally, console applications running well with this function. Below you can see my snippet code and stuff it prints.

my $w_Button_002 = $mw -> Button ( -background, 'Yellow', -foreground,
'Black', -command, sub{system('echo Hello'=>'')},  -text, 'Magic 0' )
-> pack();
my $w_Button_003 = $mw -> Button ( -background, 'Red', -foreground,
'Yellow', -command, sub{system('xterm'=>'')}, -text, 'Magic 1' ) ->
pack();
MainLoop;
