I am uing AI 9.1 work station. BAck up all files to external disk, varify image... .... no problem. When I boot from AI CD, first of all, it looks fine. But after I choose AI work station full version and go into following manu, the mouse cursor changed from a hand to an arrow, and only can be moved from top to bottom in the middle of the screen and can not move to any other area of the manu. Neither could I go any further from here if I do not use keyboard. Wodering if anybody can help me out??!!
