This drag-to-delete method works in all versions of Mac OS X. Most 3rd party apps can be smoothly uninstalled in that way, but you cannot delete built-in apps by doing this. Some apps installed using the Mac package installer will prompt you for a password when you try to move it to the Trash. In any case you cannot move Uberstrike HD 4.6.2 to the Trash or empty the Trash, try holding the Option key as you choose Empty Trash from the Finder menu, or reboot your Mac and try it again later.
