I have just tried the “Add new spot” function.
When initiated, the expected box appeared, and I completed it before hitting the “Add spot” button at the bottom.
The page contents then went completely blank, except for a “Done” at bottom left. There was no apparent way back (the IE7 back arrow at top left did not produce any obvious result) until I went to Favourites and re-navigated to the page.
When I got there I found that my spot had not appeared, although Roy’s (presumably from the old system) had.
