Comment 22 for bug 296610

The Dell Precision M4400 has the same bug. I'm intrigued by http://ubuntuforums.org/showpost.php?p=7808011#7808011 which indicates that replacing the hardware fixed the problem. Multiple hardware revisions going around?

The patch that's floating around is half of a workaround--you can still get into situations where the mouse buttons will seemingly stick, but at least the mouse doesn't jump or randomly send clicks anymore. I further modified it to try to deal with this, but it's a horrible kludge (and I haven't tested it against newer kernels.)
