How to enable mouse wheel in virtualbox?

I've installed on my host ubuntu 10.04 in virtualbox guest operating system ubuntu 12.04. And mouse wheel doesn't scroll vertically the contents of a window. In host works normally. VirtualBox mouse indicator in the right bottom corner flashhes when I'm using mouse wheel.

Solution 1:

I also had this same problem, other distros in VirtualBox accepted mouse wheel scrolling without a problem.

My fix was in the "Machine" menu of the VirtualBox window in which Ubuntu was running, select "Disable Mouse Integration". Mouse wheel scrolling works after that.

I am using a wired mouse into a PS/2 port on the host.

Solution 2:

You should update to the latest VirtualBox and extension pack, and reinstall vbox addition. Everething works fine after it, tested minute ago.
