Is it possible that > something is wrong with your mouse wheel or the driver? I'd be surprised, since Emacs is the only program that I've seen this occur in. I scroll a fair bit with the mouse wheel in Firefox and have never seen this there. >> P.S. Is there a way to get the event time in C-h l?

There may have been some scroll events that occurred before I refocused the frame that wouldn't have close times, so it might be nice to distinguish them. I was also thinking that it might be helpful in other bug reports involving events. > What kind of mouse is this? Is that by any chance a mouse pad of a > laptop? No, just a regular desktop mouse with a scroll wheel.
