HISTORIC ENGLAND AERIAL PHOTOGRAPHS - NEED HELP

I don't recall being able to turn off RAF/USAAF and modern HE photos independently, only the obliques or verticals as a block. Having said that I don't think I ever tried. There were some issues a few days ago when the available frame thumbnails didn't appear and therefore couldn't be opened but this evolved into a long delay before frames appeared a day or so later. That seems okay now. 

With the number of frames in some areas, especially London, I just click on a point in my area of interest and cycle through the 20+ frames for that point, frustrating if the Greens have taken over though.

It would be good if you could isolate coverage to selected types of vertical and oblique.

I also understand NCAP is due to release a new interface later this month, or the next. Hopefully they will add a location search. 
 

There is a two second delay on the thumbnails opening for me today but it was 6-8 seconds the other day. The other change is that Windows 10 updated without me knowing around that time. Not sure if that is relevant though. Have you tried other browsers? 

I use to be able to work these sort of problems out in the days of DOS and early Windows but they have made things "user friendly" now, so only experts stand a chance of solving these issues.
