i have Adobe Photoshop 7.0 .. i installed it.. and when i use it.. it is fine at first.. but after while it just freezes my whole computer.. maybe it is becuz of a configuration?.. but it freezes for no reason.. and thers no way to restart or turn off.. but to press the restart button.. and the copy of the photoshop isnt bad because ive used it on other computer and it works fine.. any way to solve this problem?
