Horizontal scrolling through history


#1

For the longest time, I’ve been plagued with the fact that I can’t use my laptop’s touchpad when scrolling in SumatraPDF, because it inevitably jerks me around in the file far more than I intended to scroll.

Finally, my oblivious brain noticed a pattern to what was going on: occasionally, it would send me flying forward or backward through the history (as Alt+Left or Alt+Right will do). From there, it was relatively simple to figure out that scrolling horizontally on the touchpad moves through the document history.

Since it is just about impossible not to scroll at least a few pixels horizontally when attempting to scroll vertically (when using two-fingered scrolling), is there any way to either reduce the sensitivity or simply disable this feature, without disabling navigating through history entirely?
