Hi Monks, The below non-working code just asks for the user entry, waiting for it. Now there is a very strange problem i face as described below. 

sub pop_user_entry{
        $temp_var = "";
        my $user_entry_done = 0 ;
        my $dialog_top = $mw->Toplevel(-title=>"User Entry");
        $dialog_top->Entry(-textvariable=>\$temp_var)->pack;
        $dialog_top->Button(-text=>"OK",-command=>sub {$user_entry_don
+e = 1 unless($temp_var =~ m/^$/);})->pack;
        $dialog_top->waitVisibility;
        $dialog_top->grab;
        $dialog_top->waitVariable(\$user_entry_done);
        $dialog_top->grabRelease ;
        $dialog_top->destroy;
}

The problem is that when pop_user_entry is called, i CANNOT enter into the Entry widget via keyboard. But strangely if i pack the Button before Entry, then all works fine. Working Code: 

$dialog_top->Button(-text=>"OK",-command=>sub {$user_entry_done = 1 un
+less($temp_var =~ m/^$/);})->pack;
$dialog_top->Entry(-textvariable=>\$temp_var)->pack;

But because of common sense, i want the Entry before Button as shown in original code which does not work. Please let me know if you can spot the problem in the original code:
