Actually I've now cracked it. The grab handles weren't visible because the flight track was very long. Now that I am revising it in shorter legs the grab handles are there.
Good news that (a) there's going to be yet another new version, and (b) the edit button will light up again.

Very many thanks, Tim.

Thank you for your reply, Tim.
I had no problem with editing in the first release, and it was very useful to have the edit button lighting up when selected. I've tried again and again to get grab handles to appear, but with no luck at all.
Any further advice would be very welcome.
I have to say that Plan-G is a superb facility. I can't fly anywhere without it on my second monitor. Thank you very much for providing us with it.

I can't get the edit button to work in the latest version. It doesn't light up when I press it, and no squares appear on the flight line.
Help please.

Jock

The program is exceptionally good. Very many thanks, Tim.
I have been using Plan-G with FSX on Vista for some time now. However, I can't build FS9 database because it is greyed out. I assure you, FS9 IS installed and fully working on my computer.
Any way round this problem, please?
