I have an interesting problem that seems to have arisen since I upgraded to Windows 10. The flight Cost (in the Flight Details section) is showing $ instead of £. I've used the "Fuel Prices" option on the "Mapping" menu to check prices, and they are all showing in £. I have also tried the "Change Units" menu item in the "Set Up" menu, but that doesn't show currency as an option.

What am I missing?

A setting buried deep in Windows, I expect. Something under regional settings perhaps.

I think you're right. It's actually OK now. The problem is that I changed two things before I checked back again, so I don't know which one made the difference. Moreover, I can't even remember one of the changes I made!
