Hi. In my attempts to create an email client, netbean's GUI builder has made me very unhappy... so, I decided I'd rather code it by hand... not my best idea, but whatever. Now, I'm trying to nest a Vertical JSplitPane in a Horizontal JSplitPane, and I can't see the left side of the Pane that is split down the middle. When I run the program, I only see the handle for the bar that resizes up and down... I want it to look something like this, I got it to work in the GUI builder, but I've stopped using that...:
__________

Also, the GridBagLayout is starting at the top left corner, but in the center... does anyone know how to fix that????
Here's my code:
lines 79-99 are the problem area for the JSplitPanes i believe
