Hi BrowserUK,

Thanks for that. A sensible suggestion. I just did that and made a global replace. I also moved the Wx::Font line before the rest of the code, like this: 


    my $loc_font_wx=Wx::Font->new($gl_cfg->{client_point_size}, wxMODE
+RN, wxFONTSTYLE_ITALIC, wxFONTWEIGHT_BOLD, 0, $gl_cfg->{client_font})
+;
    $mu->record('after i_Booking set focus');
    
#     Referring Dr details from Dr file
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Lbl} = Wx::StaticText-
+>new($booking_dlg->{booking_main}, wxID_ANY, __t('Referring Doctor'),
+ wxDefaultPosition, wxDefaultSize, );
    
    $mu->record('before i_Booking i_staticText 1');
    
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Txt} = i_staticText->n
+ew($booking_dlg->{booking_main}, wxID_ANY, "", wxDefaultPosition, wxD
+efaultSize, );
    $mu->record('after i_Booking i_staticText 1');
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Txt}->SetFont($loc_fon
+t_wx);
    $mu->record('before i_Booking Ctl_Booking_Referring_Doctor_Ref_4_L
+bl');
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Ref_4_Lbl} = Wx::Stati
+cText->new($booking_dlg->{booking_main}, wxID_ANY, __t("Ref 4"), wxDe
+faultPosition, wxDefaultSize, );
    $mu->record('before i_Booking i_staticText 2');
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Ref_4_Txt} = i_staticT
+ext->new($booking_dlg->{booking_main}, wxID_ANY, "", wxDefaultPositio
+n, __xy_size(100), );
    $mu->record('after i_Booking i_staticText 2');
    $booking_dlg->{Ctl_Booking_Referring_Doctor_Ref_4_Txt}->SetFont($l
+oc_font_wx);

But even so, the variable should be destroyed when it moves out of scope and it is not, so I suspect some sort of circular reference. I just can't see it.
