I’m guessing that you are right. I deleted the ‘D’ and did a few searches before my last post here, but today even if I just use the url www.openstreetmap.org if comes back as soon as I zoom to see details such as footpaths so its use is now rather limited!
Thanks again, CC
The button to toggle the data layer on & off is quite laggy, so I sometimes find in trying to turn it off I’ve turned it off & back on again. SomeoneElse’s advice to just delete the “D” stuff is good in this respect.
As an OSM newcomer many years ago I accidentally turned on a “lint” layer (for finding mapping issues, long since retired) and wondered what the hell I’d done.
