The status bar seemed like a good 'home' button because it is visible on every screen. I am definitely open to other ideas though.
Funny you mention the INI code. Originally, it was 1 line of code to read a setting, and one line of code to write a setting. But that was using Win32API functions ReadPrivateProfileString and WritePrivateProfileString. I wanted to get away from the API where I could, but didn't want to risk bloating the program with any XML, so I wrote all the IO myself. I agree that there's probably a better way for the user to enter this info, and to store it, but I don't know if XML is the answer (yet). It would be pretty simple to remove the need to enter the array size, and just have the app check 0 thru 100.
