Hi Peliard,
I tried your suggestion, but it didn't help!
A long running process on my PC finished, so I tried a reboot. Still no luck!
Then I tried re-installing (which I figure was probably on your mind) -- and now it WORKS!! BRILLIANT!! (Multi-lines and a proper menu on right click. And centering and other options now work. Really excellent.)
Thanks so much for your patience and persistence in narrowing down the problem. It looks like I don't have any karma yet, but if I did I'd give you a bunch!
Thanks again. I can now relax after a few days of frustration.
Incidentally, when I originally installed v2 of Start11 it was over v1.5. I wonder if that was part of the problem.
Anyway, all the best and I hope that the world treats you as well as you treat others.
Thanks,
Rob
