It works quite well for me, it comes up with a suggestion of ~150 for the trackpoint range. Here I assumed that a minimum corrected delta ~ 1 is "precise enough". That may not be true. Subjectively, for me, a range value of 200 or higher works even better for small movements, so the suggestion might actually be corrected so that subpixel movements would be possible. But I'll leave these subtleties to you, as you've much more expertise in the area than myself.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
