My code is almost identical to BrowserUK... When I step through the program the error appears when the perl.pm hits this line my $home = $ENV{HOME} || (getpwuid($>))7; Obviousley I don't understand how to update the code to solve this. I tried to modify HOME with HOMPATH I don't know where to apply BrowserUKs suggestion $ENV{USERNAME} for the first use (in _current_user()); $ENV{HOMEDRIVE} . $ENV{HOMEPATH} for the second (in _init() ); Thank you so much for your time..
