I have made my code shorter to try and just show the error. I am using 4 panels in a container and i have coloured each panel to show they are there. My problem is my left panel which is set to LINE_START in the container. This panel's layout is set to GridBagLayout. I am trying to create a registration type panel. I am starting off with my registration title, i have set the gridx and gridy both too 0 but my title is being put in the middle of the panel. I cant seem to get it too work from the top of the panel. Please if you could look at the code and see why this is happening. The code should compile if you like to take a look.
Thanks very much.
