Swing Applications Always Starting Maximised

Swing applications always start maximised on one of my computers, but no开发者_运维百科t on others. I've posted about this issue on the Sun Java forums without any solution being found. I tried uninstalling the JRE and reinstalling it to see if that would fix it, but it hasn't. Does anyone have any ideas?

Out of desperation I reset all of my graphics card settings to their defaults, and now everything is magically fixed. It'd be interesting to know which setting fixed it.
