That's your problem I think! The calendar won't let you enter flights unless the distance has been auto-calculated (and doesn't seem to allow you to override that) but - for me here at work on a PC - that doesn't seem to work which I assume is due to a firewall or some other blockage somewhere.
Aha! Thank you! I have just succeeded in adding a flight! This is very exciting. ^
I had to look the mileage up separately on the Great Circle Mapper site, then entered it manually in the Distance section, and pressed the Return key. And it worked! (I have to press the Return key - not the 'add to log' button.)
So this is all excellent! Bit time-consuming but I'm sure my fabric softener commercial can wait...
Thanks again!
