Here’s my test program. I want to have three panels. One panel is the main panel and it has two subpanels. The chat panel and the button Panel. I use BorderLayout. At first I didn’t set any sizes because I thought the componenets would all expand to the right size, but that didn’t work. I explicitly set the sizes of everything below and that still doesn’t work.

WHat could be causing the problem?
