A question about Corners.

Is there any way to change the program that starts on one of the corners? I spent some time trying to figure it out, but haven't had much luck at it. I have my four corners setup to work, but I would like to change one of them to open a writing program that I dl'd instead.

Thanks in advance for any/all help.

I don't think you can use the built-in corners in the sys. prefs. to open an application.

I use Quicksilver to allow me to open Apps ad URL's with corner and sidewall clicks. I have the lower right corner set to Open Mac-Forums. The Left sidewall to open google, etc.
