BTW ... I tried this little utility out (on Sunday I think) and have to say it's pretty nifty, good job Keith.
If you want to get ambitious you could have it (as an option on the settings dialog of course) install a shortcut in the startup folder.
Also, you could have it "learn", by pointing to a running instance of a program: "Yes, that window right there <click>. When it gets focus force caps lock on/off".
When you're not doing anything else of course.
