It seems that while trying to install a program by dragging a specified\nicon to the applications folder, I accidentally added the program to\nthe sidebar. I have two questions about this action:\n\n1. How on earth did I do it, since I thought you COULDN'T add items to\nthe sidebar?\n\n2. How do I get rid of it? Everytime I click there by mistake, the\nprogram starts, which is a pain.
