On the first launch of the Pro Tools on some systems the computer will cease activity and appear to be frozen although the mouse cursor still remain active. In these cases the authorization window appears only after an undetermined amount of time. Letting the computer remain in this "frozen" state for as long as one hour often remedies itself and finally prompts the user for their authorization code. The most common CPU configuration exhibiting this behavior has been the Blue&White G3/400MHz (although this is not an isolated case targeting this particular model).
