I know this has been posted before, most recently here: (see OS Lion, track pad and Virtual Box) , but I am continuing to have problems with using the trackpad on my macbook pro in my guest Windows 8.1 VM.

Virtualbox: 4.3.12
Guest: Windows 8.1

Bascially, the darned thing just doesn't work, two finder scrolling horizontally, vertically, nothing. I have installed the guest additions. That fixed the screen sizing problem I was having but this pesky mouse integration issue remains.

Update:

Oddly enough, I found that what was messing up the two finger swipe was the Guest Additions. After uninstalling these it worked again, but the screen sizing was back to being messed up. I guess if I have to pick between the two I am going to go with the two finger trackpad scrolling. It would be nice if they both worked though.

I've tried it with and without GAs, just as you did. The vertical scrolling works regardless, so I cannot confirm what you're seeing. The horizontal scrolling is another thing. With GAs it acts more like a PgUp/PgDn vertical scrolling. Without the GAs it works as expected; horizontal scrolling. Haven't looked in the Bugtracker to see if there is anything there. Will look later on and update if necessary. BTW, host is running Snow Leopard on a MBP 17 from early 2011, guest is Win8.1.

Tested in OSX 10.9.3, VB 4.3.12

Horizontal scrolling doesn't work with Windows 7 or Windows 8.1 with guest additions installed.
not with the Apple Mouse, the Magic Mouse, the Touch Pad or a Track Pad.

I tested the Touch Pad with PS/2, USB Tablet and USB Multi-Touch settings. the other devices with USB Tablet set.

they work fine in Linux guests.

Update: I noticed that I had the parallels additions installed as well. After I removed these, everything with the horizontal scrolling worked with Virtual Guest Additions.
