I have a mac powerbook g3 laptop and have successfully installed Virtual PC on. My problem is that when I open Virtual PC it just comes up with a black Virtual PC programme window. Once its done that I am unable to do any thing with Virtual PC because its frozen and in order to get out of the programme I have to force quit it. What do I do to get it to run windows 98? (I have both the Virtual PC disk and the windows 98 disk).
