I think there is a bug in the G4P designer tool that when you use more than one secondary window a method with a wrong name is created:

This is what is created after adding another secondary window. This method is already present in gui.pde what creates the “Duplicate method” error.  
synchronized public void win\_draw1(PApplet appc, GWinData data) { //_CODE_:window2:307473:  
appc.background(230);  
} //_CODE_:window2:307473:

And this is how is should be. Changing win\_draw1 to win\_draw2 fixes the problem. However, whenever the G4P tool is used it revers to the old (wrong) method setting.  
synchronized public void win\_draw2(PApplet appc, GWinData data) { //_CODE_:window2:307473:  
appc.background(230);  
} //_CODE_:window2:307473:

i try that here (win 10 / processing 3.5.3 / G4P GUI Builder 4.3 /  
make 2 add windows  
window1  
window2  
and got a win\_draw1 and win\_draw2

after deleting the windows and make again, got  
window1  
window2  
and got a win\_draw3 and win\_draw4

all works.

but i added in all 3 windows a label and got

```auto
// Variable declarations 
// autogenerated do not edit
GLabel label1; 
GWindow window1;
GLabel label1; 
GWindow window2;
GLabel label2; 

```

> Duplicate field \< sketch name \> .label1

so in main i need to rename the label1 to ‘label0’  
then it works.

BUT EDIT NOT IN THE CODE,  
only via the amazing GUI BUILDER Properties menu

If you read the comments in the gui tab it states that the only code you are allowed to edit is _INSIDE_ the event handlers. Changing method, variable names etc must be done in GUI Builder window.
