I found another program that may be useful but I ahven't run it yet - I've spent the entire time between Xmas (BOxing Day) and now fighting with my main computer that now seems more or less to be running - more on another thread. However, the program I may try (although the affected computer has now gone north with daughter, AOK except for TV card) is called "Driver Detective". I may need it for another reason (again see another thread).
