Hi Margaret,
Yes, the new site takes a bit of getting used to and is not as user friendly as you say.
You can do what used to be an ordinary search - at the left hand side there is the word people in black writing and you just enter your search details along from this. It takes you to all the births, marriages and deaths for that name and you click on the record you want e.g. deaths and it then brings up the list. Personally I use the advanced search now. Hope you can understand what I mean.
I cannot understand why the death record you want for the lady who died in 1966 is not available. What are the exact words that come up ?
Or if you want to post her details here I will give it a go and see what it tells me.
