OS X 10.10.2 host, Ubuntu 14.10 guest. I have installed guest additions.

To reproduce:
1. Open nautilus file browser.
2. Click Computer, then double-click bin.
3. Scroll up and down with 2 fingers.
4. When you scroll up you will get taken back to Computer (root).

The same thing can be seen with Firefox. Scrolling up and down will take you back and forward in your history.

Me too but with Windows Host.

Treid it with Windows 10 TP and Kubuntu 14.04. Logitech Optical Mouse. When I scroll the mouse then I am taken back in Firefox and some Windows 10 Setting dialogs.

Can confirm scrolling issues OSX Host, Multiple guests with a normal Apple Mouse with scroll button and the Magic Mouse.

Scrolling issues on Linux hosts as well.

This should be fixed in the next beta.
