I've just switched over from a PC to a new MBP, purchased last week, and I'm sure this has been answered, but I can't find it. I have searched the forum, Google, and Mroogle. When installing a disk image (.dmg file), I download the file, double click on the file in the download folder, located in the dock, that presents another window with a shortcut to the applications folder, I drag the file to the shortcut, and I get another window that lets me know that OSX is copying files. Everything in the finder\applications folder looks fine, and I can click on the icon, open and use the app. When I look at the applications folder in the dock, however, the icon is just a sheet of paper with a circle in the middle with a line running through the circle. A reboot seems to correct it, but is that normal to have to reboot after installing a .dmg file to get the icon to show up correctly in the app folder in the dock?
