One thing I do notice is that when I exit out of DosBox/RubyBox and go back to surfing the web, clicking on links doesn't work anymore. A re-boot fixes the problem. However, is there something I can do (like killing a process in xterm) that may be able to remedy this without a reboot? Incidentally, I noticed this problem once I started using RubyBox. Also, I'm not using Addison's latest keyboard mod yet...
