Crashes on Horizontal Scroll in Piano Roll

[Garfield Davidson]

I have a Dell laptop and as long as I've been using CWBBL (about this long) every time I try to use the two-finger mousepad gesture to scroll sideways in the Piano Roll, the whole program hangs for a few seconds, and then crashes. No recent dumps (old ones have code 0xC0000005). I can hold Ctrl while I two-finger-swipe up/down to go horizontally, but that's an extra step, not to mention less intuitive, and I still forget sometimes and lose progress.
