If only it were that simple. Your sequence -
--- 1) Select the name
--- 2) Right click
--- 3) Choose "Change the name" from right click menu
--- 4) Erase England
--- 5) Click ok
Is precisely what I have done - many times. The problem is that as soon as I click "OK" ", England" pops back up on the end of my place name. It is impossible to get out of that screen with a shortened place name.
You also suggest that I "just hide it" - How? As I said in my post, the only option I can find for that does not work.
And yes, I do want to remove England permanently; the country name is only relevant for places outside the UK (about 30 of 720).
