Thanks for all the replies. This suggestion worked. I actually thought from GridBagLayouts' flexibility that it was easier even though it required more lines of code. Ive learned the hard way that SWING programming in itself is not all that intuitive. Thanks again for your help.

The code I have here may not be the exact layout you want, but at least it does not shrink the scroll pane. Remove this line: logScrollPane.setPreferredSize(new Dimension(70,50)); Remove these: gbc.gridy = 3; gbc.gridwidth = 2; gbc.gridheight = 4; fcPanel.add(logScrollPane,gbc); Change the layout of installContentPane at the end of the "startInstall" method to: //fcPanel.setMinimumSize(PaneDim); fcPanel.setPreferredSize(PaneDim); installContentPane.setPreferredSize(PaneDim); installContentPane.setLayout(new BorderLayout()); // added installContentPane.add(fcPanel, BorderLayout.NORTH); // changed installContentPane.add(logScrollPane, BorderLayout.CENTER); // added installerFrame.setSize(600,300); logScrollPane.revalidate(); GridBagLayout is not easy to use, although it is flexible. Just in case you do not know, here are some good tutorials about layout mangers. http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html http://manning.com/sbe/files/uts2/Chapter4html/Chapter4.htm Hope that helps.
