I don't know. Are you using Windows? When you middle-click to get the headers, it just tops the msg and displays the text. For some reason, your system is seeing the return from the top method as an arrayref. If I'm interpreting your problem corrrectly, try changing this code:

sub browseThis{
print chr(07);         
my @msgs = $h->info('selection');
my $msg = $msgs[0];    
     
my $messref = $pop3->top($msg,10);
$text->delete('1.0','end');

####RIGHT HERE#################
#$text->insert('end', $messref);
$text->insert('end', @$messref);
}

Come to think of it, maybe I should change that, I never thought about it, because on my system, the $messref prints out as a string.
