I too had problems with my meter when I switched from Win 7 to 10. I've used Maxthon for years and in Win 7 it was smooth as butter but with 10 it would be smooth one shot, terrible the next. And it wasn't just the meter, sometimes the ball sailed across the sky like a badly made stop motion film.
A friend suggested I use the newest Flash version, I was still running trusty 11 something, and it certainly helped a lot. I make sure I keep my Flash version current and rarely have any problems.
And sorry, I can't resist:
PeteM2:
what is Maxthorne please.
I believe Max Thorne was a 1980's Austrian porn star.
