Many thanks Frances for your very useful insight into the workings of a computer.
I do have Flash etc. installed which is, as you suggest, probably why I was able to access the Familysearch website. However, until the LDS has a lot more data I, for one, will not be using it very much for my purposes as what is already on there is 99% US information and of no interest to me as my research is only the IOM and UK. I appreciate it may be of current help to others who have ancestors who travelled overseas though.
Thanks anyway Frances, always helpful!
