No, I think that I found the remaining problem, and now my mouse is running as well as it can do, even for mouse clicks. Apparently, I had the position of my trackball (I dislike mice) right up next to my keyboard, which applied a small amount of constant pressure against the ball of the trackball. When I moved the trackball so that there was no remaining pressure, everything became perfect. Summary (after testing) is that moving from SCHED_ULE to SCHED_4BSD is maybe 1/2 of my problem, and moving the trackball fixed all remaining problems. Thanks hugely for the help, Gavin. > > Gavin -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmm1T8ACgkQz62J6PPcoOlLmQCgjLwrI8j24bZyp1N8M4rZjvvr LR0AnjWZYhORgZQv9ymIT4fUiVi8e7ge =BgAF -----END PGP SIGNATURE-----
