[PD] [leapmotion] how to get focus?

[William Brent]

I just set up my Windows machine to match your system as closely as
possible, and all still works as expected with [leapmotion] for me. The
only difference is that I'm on Windows 10 rather than 11.

After reading your message again, I see that you're occasionally getting
some tracking data, so most of what I said in my previous post is
irrelevant. But before I dig any further: are you *sure* you're clicked on
Pd to make it the foreground application when testing [leapmotion]? If
you're clicked on the desktop or any other window/app to lose focus, then
tracking data will stop flowing. And if those focus gained/lost messages
aren't making sense with the actual clicking you're doing, that's what we
need to look into. Maybe I can just disable the need for focus entirely...
