Hi, Sorry to bother you but if you could give me some indication of what I need to do with regards PTE on Vista?. I have just purchased a new lap top to use for my lectures instead of my PC. X.P. Every thing has worked fine on PC from the start, but on laptop ( Vista, of course not through choice). I open folder as normal. All the icons appear showing short sequences click on one, plays O/K click esc every thing locks up, not every time but to much to be reliable at lectures. I hope there is a solution to this and would be very grateful for any suggestions.
