using CGI.pm I create radio buttons The fist one remains persistently highlighted. I've tried this to clear it ( ie start off with an empty form ) but it doesn't clear the button 
my %vars = $q->Vars();#print Dumper %vars;
 $q->delete_all;
print $q ->start_form;
print $q->radio_group(-name=>'options', -values=>[keys %details] ,-col
+umns => 4,
-rows    => 2);

this also has a button persistently selected that doesnt clear with a 'form reset' 
foreach my $s (keys %details)
{print  "<input type=\"radio\" name=\"options\" value=".$s,">".$s."  "
+; 
 }

[download]
but this doesn't 
foreach my $s (@opts)
{print  "<input type=\"radio\" name=\"options\" value=".$s,">".$s."  "
+; 
 }

so going back to the original 
print $q->radio_group(-name=>'options', -values=>\@opts,columns => 4,-
+rows> 2, -default=>'');

is there an explanation?
