MATLAB: GUI closing unexpectedly once published as an application

applicationcompilerguiMATLAB

Hi, I have written a fully working GUI. I then wanted to add more functionality by bringing up a further GUI when a push button is pressed. This all seems to work fine when run from inside MATLAB. However, once the application is published using applicationCompiler, when that button is pressed the second GUI appears for a fraction of a second and then disappears/closes. The second GUI is called using:
% --- Executes on button press in pushbutton7.
function pushbutton7_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton7 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
FuncGen2;
I attach the code for the second GUI (FuncGen2) as well.

run the exe from a command prompt and it will write any error message to that window - that should help you debug.
