As a recent switcher, I'm concerned that I may not be installing programs properly. My understanding is that after you download a .dmg, you drag the application icon into the Apps folder and that's that. Except what shows up in my Apps folder is a little "crossed-out" icon instead of the actual app icon. It works fine, I can launch it...but until I reboot, the icon remains crossed out. Just wondering if this means I'm doing something wrong?
