Dear Maintainer,

there is already a launchpad BUG[1], describing my problem. In short:

* KVM virtualisation (host and guest are wheezy)
* spice is enabled as "display" (no SDL, VNC)
* an usbtablet is used as absolute pointer
* insinde the guest runs spice-vdagent (X11 session)

Killing the agent scrolling works. without the agent you lose clipboard shareing between spice client and server.

TIA, Sascha.

Poking around with ximput. I discovered movements of my mouse
were being seen in wheezy VM as "tablet".

The VM config (in virtual Machine Manager)  did indeed have a tablet
defined.

I deleted this tablet (and also a 2nd mouse created while banging my
head against the wall  WRT this bug)
and using xinput inside wheezy I saw a new 'tablet appear'

Testing using xinput I can see that my mouse events are appearing on
this tablet and not on the "ExPS/2 Generic Explorer Mouse"

If I stop spice-vdagent , the "spice vdagent tablet  disappears, mouse
input then appears on "ExPS/2 Generic Explorer Mouse"
and the mouse wheel starts to work (appears as buttons 4 & 5)
