Hi, I'm kind of a newbie in perl but i noticed your code had some trouble running on my pc... the corrections made were in the creation of the api SetWindowPos object which now becomes Win32::API->new('user32', 'SetWindowPos', ['N','N','N','N','N','N','N'], 'N'); or you might as well code it [NNNNNNN], N, i think it will work (havent tested...) and the creation of the FindWindow obj also: Win32::API->new('user32', 'FindWindow', ['P','P'], 'N'); again [PP], N... that made it work on my pc... anyway, thanks for the code!
