On a older Sony tower when I use the bootable CD (program not insatlled in computer) the mouse cursor doesn'tr show. I manage to get to the comments scrfeen, but can't get off the comments box to the 'next' box to proced to the next imaging step. I treid as many keyboard shortcuts I can think of but nothing seems to move the cursor from the comment box to the bottom row of radio buttons. Any ideas on either issue? This is V8.
